DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 617 DS1 Circuit Pack 17 Line Compensation The appropriate entry in this field varies with the type of cable used, so work with your network service provider to determine the correct setting in your situation. The following table shows the appropriate entries for different lengths of 22-gauge ABAM cable terminated on a DSX-1 cross-connect. The following table shows the appropriate entries for different lengths of 22-gauge ABAM cable directly connecting to DS1 interfaces. Framing Mode Use this field to select either superframe (sf or d4) or extended superframe (esf) for T1 service on the DS1 link. The framing mode you use must match the mode used on the other end of the link, so work with your network services provider to determine the appropriate entry for this field. This field only appears if the Bit Rate field is 1.544 (that is, if you’re using T-1 service). If you’re using E-1 service, DEFINITY ECS automatically selects CEPT1 framing. Tip: Lucent recommends using ESF when your service provider supports it, especially if you may someday upgrade the facility to ISDN. The ESF format provides enhanced performance measurements and uses a sophisticated error-checking method to ensure data integrity. Valid entries Usage 1 Length: 000–133 (ft), 000-40.5 (m) 2Length: 133–266 (ft), 40.5–81.0 (m) 3Length: 266–399 (ft), 81.0–122 (m) 4Length: 399–533 (ft), 122–163 (m) 5Length: 533–655 (ft), 163–200 (m) Valid entries Usage 1 Length: 0000–0266(ft), 000–081(m) 2Length: 0266–0532(ft), 081–162(m) 3Length: 0532–0798(ft), 162–243(m) 4Length: 0798–1066(ft), 243–325(m) 5Length: 1066–1310(ft), 325–400(m)
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 618 DS1 Circuit Pack 17 Signaling Mode This field selects the signaling method used for the DS1 link. This mode must match the method used on the other end of the link, so work with your network services provider to determine the appropriate entry for this field. D-Channel The Japanese 2Mbit trunk circuit pack, when administered to support ISDN-PRI signaling, allows you to assign the D-channel to any channel from 1 to 31 in an E-1 facility. You cannot submit the screen if this field is blank. Using the change ds1 command, you can change this field if the D-channel is not used in a signaling group. This field appears only when the Location field indicates the circuit pack is a Japanese 2Mbit trunk circuit pack and the Signaling Mode field is isdn-pri. Valid entries Usage d4 Enter d4 to use the basic DS1 superframe (sf). This mode is recommended only for voice traffic. esf Enter esf to use the Extended Superframe format. This mode is recommended for digital data traffic. If you enter esf for a TN464F, TN767E, or a later suffix DS1 circuit pack, a second page of the DS1 Circuit Pack screen becomes available to administer ESF Data Link options. Valid entries Usage CAS (Channel Associated Signaling)Enter CAS for out-of band signaling with E-1 service. This setting yields 30 64-kbps B-channels for voice or data transmission. Channel 0 is used for framing while channel 16 carries signaling. robbed-bitEnter robbed-bit for in-band signaling with T-1 service. This setting yields 24 56-kbps B-channels for voice transmission. isdn-priEnter isdn-pri for either T-1 or E-1 ISDN service. This setting supports both Facility Associated Signaling and Non-Facility Associated Signaling. isdn-extEnter isdn-ext for either T-1 or E-1 ISDN service. This setting supports only Non-Facility Associated Signaling. common-chan Enter common-chan, for out-of-band signaling with T-1 service. This setting yields 23 64-kbps B-channels for voice or data transmission. Channel 24 is used for signaling. Valid entries Usage 1 to 31 Enter the number of the channel that will be used as the D-channel.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 619 DS1 Circuit Pack 17 Connect In order to control communications at layers 2 and 3 of the ISDN-PRI protocol, use this field to specify what is on the far end of this DS1 link. This field only appears when the Signaling Mode field is isdn-pri. Interface This field only appears when the Connect field is pbx; that is, when this DS1 link is providing an ISDN-PRI connection in a private network. The Interface field controls how your switch negotiates glare with the far-end switch. The switches at either end of the DS1 link must have complementary settings in this field: if not, the D-channel won’t even come up. For example, if the switch at one end of the link is administered as network, the other must be administered as user. Valid entries Usage pbx Enter pbx if this DS1 link is connected to another switch in a private network. If pbx is entered, the Interface field appears. line-sideEnter line-side when the switch is acting as the network side of an ISDN-PRI interface. Use line-side to connect to Roll About Video equipment. network Enter network when the DS1 link connects this switch to a central office or any other public network switch. hostEnter host when the DS1 link connects this switch to a computer. Valid entries Usage Use the following 2 values for private network applications in the U.S. networkEnter network if your switch overrides the other end when glare occurs. If you are connecting your switch to a host computer, set this field to network. userEnter user if your switch releases the contested circuit and looks for another when glare occurs. If you are connecting your switch to a public network, set this field to user. Use the following values for private networks (including QSIG networks) outside the U.S. Entering either of these values causes the Peer Protocol and Side fields to appear. peer-masterEnter peer-master if your switch overrides the other end when glare occurs. peer-slave Enter peer-slave if your switch releases the contested circuit and looks for another when glare occurs.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 620 DS1 Circuit Pack 17 Interconnect For E-1 service using channel-associated signaling, the entry in this field tells DEFINITY ECS whether the DS1 circuit pack is using a public or private network protocol. The entry in this field must agree with the entry in the Group Type field on the Trunk Group screen. This field appears only when the Signaling Mode field is CAS. Country Protocol The entry in this field must match the country protocol used by the far-end switch. For connections to a public network, your network service provider can tell you which country protocol they are using. This field appears if the Signaling Mode field is CAS or isdn-pri. For the Japanese 2Mbit trunk circuit pack, this is a display-only field if the Signaling Mode field is CAS. Peer Protocol This allows you to administer the peer level protocol that will operate in a private network. This field appears if the Interface field is peer-master or peer-slave. To enter Q-SIG, the Basic Call Setup field on the System-Parameters Customer-Options screen must be y. Valid entries Usage pbx If pbx is selected, the board operates as a tie trunk circuit pack. COIf CO is selected, the board operates as a CO or DID circuit pack. Valid entries Usage 1 to 25Enter the country protocol used by the central office at which this link terminates. etsiEnter etsi if your network service provider uses the protocol of the European Telecommunications Standards Institute (ETSI). Enter etsi only if the Signaling Mode field is isdn-pri. Valid entries Usage Q-SIG This implements QSIG Network Basic Call. TTCFor private networking. Requires a Digital Trunk (Japan 2 MB TTC) (TN2242) circuit pack.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 621 DS1 Circuit Pack 17 Interworking Message This field determines what message the switch sends when an incoming ISDN trunk call interworks (is routed over a non-ISDN trunk group). Side This field controls how your switch resolves glare at layer 3 over an ISDN-PRI link in QSIG private networks. It appears if the Interface field is peer-master or peer-slave. The default value of the field changes depending upon which value the Interface field contains. !CAUTION: It is critical that administration on this switch correctly pairs with the administration of the far-end switch. If the far-end is administered as the b side, this field should be set to a regardless of whether the layer 2 designation is peer-master or peer-slave, and vice versa. Valid entries Usage PROGress Normally select this value. PROGress asks the public network to cut through the B-channel and let the caller hear tones such as ringback or busy tone provided over the non-ISDN trunk. ALERTingALERTing causes the public network in many countries to play ringback tone to the caller. Select this value only if the DS1 is connected to the public network, and it is determined that callers hear silence (rather than ringback or busy tone) when a call incoming over the DS1 interworks to a non-ISDN trunk. Valid entries Usage a Enter a if the Interface field is peer-master (this switch overrides the far-end when glare occurs). bEnter b if the Interface field is peer-slave (this switch releases the contested circuit and looks for another when glare occurs).
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 622 DS1 Circuit Pack 17 Protocol Version In countries whose public networks allow multiple layer 3 signaling protocols for ISDN-PRI service, this field selects the protocol that matches your network service provider’s protocol. Refer to ‘‘ Public network signaling administration for ISDN-PRI Layer 3’’ on page 1331 to see which countries support which protocols. This field appears only when: nThe Signaling Mode field is isdn-pri and the Connect field is network. nThe Signaling Mode field is isdn-pri, the Connect field is pbx, and the Interface field is user or network. !WARNING: The AT&T Switched Network Protocol does not support restricted displays of connected numbers. Therefore, if you administer the 1a country-protocol/protocol-version combination on the DS1 screen, you cannot set the Send Connected Number field to r (restricted) on the ISDN-PRI Trunk Group screen, as this causes display problems. Interface Companding The entry in this field must match the companding method used by the far-end switch. This field does not appear for all DS1 circuit packs. CRC This field indicates whether a cyclic redundancy check (CRC) will be performed on transmissions that the DS1 circuit pack receives. This field does not display for all circuit packs. Valid entries Usage a The entry in this field must match the protocol used by your network service provider, so work with your vendor to determine the appropriate entry. b c Valid entries Usage alaw Enter alaw for E-1 service. mulaw Enter mulaw for T-1 service. Valid entries Usage y Enter y when the Signaling Mode field is CAS and the DS1 link is providing E-1 service. nEnter n for all other applications.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 623 DS1 Circuit Pack 17 Idle Code !CAUTION: Customers: The entry in the Country Protocol field sets the default idle code. Do not change the default without assistance from Lucent or your network services provider. For some circuit packs, this is a display-only field. Channel Numbering The ETSI and ISO QSIG specifications require that B-channels on an E1 be encoded as 1-30 in the Channel ID IE. Prior to this field, DEFINITY ECS only used this scheme for Country Protocols 2a (Australia) and 13a (Germany 1TR6). This field appears when the Signaling Mode field is isdn-pri, the Bit Rate field is 2.048, the Connect field is pbx, and the Interface field is peer-master or peer-slave. DMI-BOS The DMI/BOS protocol is used for high-speed digital communications between a host computer and a DEFINITY ECS. With this 24-channel protocol, channels 1–23 of the DS1 link carry data and channel 24 carries control signaling. DMI/BOS has greater capacity than a robbed-bit 24-channel facility. This field appears only when the Signaling Mode field is common-chan. Valid entries Usage any 8-digit string of 0’s and 1’sThis entry sets the signal sent out over idle DS0 channels. The string must be compatible with the protocol used by the far-end switch. Valid entries Usage timeslot sequential If the DEFINITY ECS is connected via QSIG trunks to a switch supporting the ETSI QSIG or ISO QSIG specifications, this field must be sequential. When the Signaling Mode field is isdn-pri and the Bit Rate field is 2.048, but the Channel Numbering field does not display because of the setting of other fields, it is set internally to sequential for 2a (Australia) and 13a (Germany). Valid entries Usage y Enter y to activate the Digital Multiplexed Interface-Bit Oriented Signaling (DMI-BOS) format. nEnter n to use a Lucent Technologies proprietary format.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 624 DS1 Circuit Pack 17 DCP/ANALOG Bearer Capability This field appears when the Signaling Mode field is isdn-pri. It is used to determine bearer capability encoding. MMI Cabling Board This field appears only if the MMCH field is y on the System-Parameters Customer-Options screen. MMI Interface This display-only field appears if the MMCH field is y on the System-Parameters Customer-Options screen and there is a value in the MMI Cabling Board field. Received Digital Metering Pulse Minimum (ms) This field appears only when the Signal Mode field is cas (Channel Associated Signaling), the Interconnect field is co or pbx, and the Country Protocol field is administered for a protocol that uses periodic pulse metering (PPM) as defined in Table 11 on page 625 . The default value depends on the Country Protocol field’s entry. Valid entries Usage 3.1kHz speech Valid entries Usage slot address (cabinet, carrier, slot)Enter the slot location (cabinet, carrier, slot) of the multimedia interface circuit pack that is connected to the Expansion Services Module (ESM). Valid entries Usage 20 to 1000 ms in increments of 10ms.Work with your network services provider to determine the appropriate entry. The entry must be less than the Received Digital Metering Pulse Maximum field.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 625 DS1 Circuit Pack 17 Received Digital Metering Pulse Maximum (ms) This field appears only when the Signal Mode field is cas (Channel Associated Signaling), the Interconnect field is co or pbx, and the Country Protocol field is administered for a protocol that uses periodic pulse metering (PPM) as defined in Table 11 on page 625 . The default value depends on the Country Protocol field’s entry. Received Digital Metering Pulse Value This field appears when the Signal Mode field is cas (Channel Associated Signaling), the Country Protocol field is 21, and the Interconnect field is co or pbx. Valid entries Usage 20 to 1000 ms in increments of 10ms.Work with your network services provider to determine the appropriate entry. The entry must be greater than the Received Digital Metering Pulse Minimum field. Valid entries Usage 0 , 1Work with your network services provider to determine the appropriate entry. Table 11.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 626 DS1 Circuit Pack 17 Slip Detection Slips — synchronization errors — slow digital transmissions and can result in data loss. The switch maintains a slip-count record for each DS1 interface to detect errors and evaluate their severity (the type of alarm). If as many as 50 percent of those spans administered for slip detection are experiencing slips (with respect to the primary), then a decision is made to switch to the secondary. !CAUTION: Always enter y for DS1 circuit packs that serve as primary or secondary synchronization references. 11 Spain 20 220 0 12 France NA NA NA 13 Germany NA NA NA 14 Czech Republic 20 420 1 15 Russia CIS NA NA NA 16 Argentina 10 180 1 17 Greece 100 180 1 18 China NA NA NA 19 Hong Kong NA NA NA 20 Thailand 20 180 1 21 Macedonia Croatia120 20180 801 1 22 Poland 100 150 0 23 Brazil NA NA NA 24 Nordic NA NA NA 25 South Africa 160 240 0, 1 Table 11.
