DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 607 DS1 Circuit Pack 17 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. 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. 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. 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 608 DS1 Circuit Pack 17 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. 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 1321 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. 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). 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
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 609 DS1 Circuit Pack 17 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. 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). 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. 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 610 DS1 Circuit Pack 17 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. 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. 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. 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).
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 611 DS1 Circuit Pack 17 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 612 . The default value depends on the Country Protocol field’s entry. 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 612 . 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 less than the Received Digital Metering Pulse Maximum field. 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.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 613 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. Near-end CSU Type This field appears only when the DS1 circuit pack is a TN767D or TN464E or later suffix model, the Bit Rate field is 1.544 and the Country Protocol field is 1 (U.S.). This field does not display for all circuit packs. Valid entries Usage y Enter y to allow maintenance software to measure the slip-rate of this circuit pack and determine whether it’s excessive. Typically, enter y for DS1 spans used for data applications and for spans used as synchronization references. This excludes all T1-spans connecting channel banks, unless the channel bank is externally timed. This entry enables switching between the primary and secondary synchronization references and an internal high-accuracy clock. n Enter n for DMI-BOS links or when testing is not required. Normally, enter n for DS1 spans that are used exclusively for voice and that do not serve as the primary or secondary synchronization source. Valid entries Usage other Enter other if no channel service unit is attached to the DS1 facility or if the CSU is an external unit. No options are available on page 2 for administering an external CSU. integratedEnter integrated if a 120A CSU module is attached to the DS1 board. This integrated channel service unit (ICSU) can accept software-administrable option downlinks (that is, it can respond to test codes from technician’s equipment and report its status). When you enter integrated, fields for administering options on the ICSU appear on page 2 of the DS1 Circuit Pack screen.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 615 DS1 Circuit Pack 17 Network Management Protocol This field appears only if the Framing Mode field is esf. Send ANSI-T1.403 One-Second Performance Reports This field selects whether your DS1 circuit pack will send error reports to the far-end switch. These reports are useful for network management, and are sent at 1-second intervals when enabled. This field appears only if the Framing Mode field is esf. It is used only with circuit packs that have an integrated channel service unit (CSU). Far-end CSU Address This field, which, appears only if the Framing Mode field is esf. Transmit LBO (Transmit Line Build-Out) This field reduces the outgoing signal strength by a fixed amount. The appropriate level of loss depends on the distance between your switch (measured by cable length from the smart jack) and the nearest repeater. Where another switch is at the end of the circuit, as in campus environments, use the cable length between the 2 switches to select the appropriate setting from the table below. This field appears if the Near-end CSU Type field is integrated. Valid entries Usage tabs The entry in this field, used only with circuit packs that have an integrated channel service unit (CSU), allows the data link to be remotely monitored. Valid entries Usage y/n Enter n. Consult your Lucent representative if you think you may want to use these reports. Valid entries Usage a Enter b. This field administers the transmit direction address used for the ESF data link command with both integrated and external channel service units (CSU).b Valid entries Usage 0db For distances of 2,001–3,000 feet -7.5dbFor distances of 1,001–2,000 -15dbFor distances of 0–1,000 feet -22.5dbFor mid-span repeaters
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 616 DS1 Circuit Pack 17 Receive ALBO (Receive Automatic Line Build-Out) This field increases the strength of incoming signals by a fixed amount to compensate for line losses. Upon DTE LOS DTE stands for “Data Terminal Equipment.” This field tells the switch what to do if the outgoing signal from the DS1 circuit pack (the data terminal equipment) to the network is lost. Supply CPE Loopback Jack Power If a CPE (Customer Premise Equipment) Loopback Jack is installed, the DS1 board should supply power to the equipment during loopback testing. Related topics Refer to ‘‘ Setting up digital trunks’’ on page 351 for instructions. Refer to ‘‘ DS1 Trunk Service’’ on page 1317 for detailed information. Valid entries Usage 26db To set this field correctly, you should measure the signal loss on this specific facility. However, you may enter 26db for most applications. 36db is occasionally appropriate, mainly on campus networks that don’t conform to public telephone network standards.36db Valid entries Usage loopback Enter loopback to return the network signal to the network. This prevents any alarms at the far-end switch. aisEnter ais (Alarm Indicator Signal) to send an unframed all-ones signal (the AIS or Blue Alarm) to the far-end switch. This option alerts your network service provider to the problem immediately and aids troubleshooting. Valid entries Usage y/n Enter y if a CPE Loopback Jack is installed. If not, you must enter n.
