DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 737 IP Trunk Configuration Manager 17 QoS ParametersnSampling Interval (sec): Allows you to specify how often the quality of service to the highlighted line pool’s remote IP address will be checked. Valid values: 1 to 300 (seconds). nSamples to Average (number): Allows you to specify the number of samples to average together when evaluating the quality of service to this remote site. Valid values: 5 to 1500. nPacket Loss Threshold (%): Allows you to specify the acceptable level of percentage of packets lost when evaluating the quality of service to this remote site. When the PSTN Fallback option is set and the threshold reaches high, the DEFINITY ECS application disables all the lines in this pool. This causes subsequent calls to be routed over the PSTN (assuming the switch is correctly configured), instead of the IP network. nLow: Valid values: 0 to 100. nHigh: Valid values: 0 to 100. nRound Trip Delay Threshold (msec.): Allows you to specify the acceptable level of round trip delay in milliseconds when evaluating the quality of service to this remote site. nLow: Valid values: 10 to 1500. nHigh: Valid values: 10 to 1500. The algorithm for the Packet Loss Threshold and Round Trip Delay Threshold evaluations works as follows: nIf either high value is exceeded, the line pool is blocked. nAfter the averaged evaluation is below both of the low values, the line pool is unblocked. Add Allows you to add line pools. Remove Allows you to remove line pools. Edit Allows you to edit line pools. Clear All Clears all the information from the Line Pools section of the QoS dialog box.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 738 ISDN trunk group 17 Related topics Refer to DEFINITY ECS Administration for Network Connectivity for administration procedures. Refer to ‘‘ IP trunk service’’ on page 1383 for detailed information on this feature. ISDN trunk group This screen assigns an Integrated Services Digital Network (ISDN) trunk group that supports the ISDN and Call-by-Call Service Selection service selection features. The trunk group provides end-to-end digital connectivity and supports a wide range of services including voice and non-voice services, to which users have access by a limited set of CCITT-defined, standard multipurpose interfaces. The ISDN trunk group may contain ISDN-PRI or ISDN-BRI interfaces. However, it is not possible to use the two types of interfaces in the same trunk groups. The type of interface is chosen when the trunk members are assigned to the trunk group. When ISDN-PRI interfaces are used on ISDN trunk groups, they may also be used to support the Wideband Switching feature. This is intended to work with the H0 (384 Kbps), H11 (1536 Kbps), H12 (1920 Kbps), and NXDS0 (128 to 1984 Kbps) data services, and to support high-speed video conferencing and data applications. Administration commands When an ISDN trunk connects two switches, set the trunk options identically at both ends of the connection, with the exception of the Trunk Hunt fields. When ISDN-PRI interfaces are used, it is acceptable for both ends to have the Trunk Hunt fields administered as cyclical, but if one end is administered as ascend, the other end must be administered as descend. This helps avoid the possibility of glare conditions. When ISDN-BRI is used, the Trunk Hunt field has to be cyclical. Hardware requirements ISDN-BRI interfaces are supported by the TN2185 Trunk-side BRI circuit pack (for implementing the user side of the BRI interface) and by the TN556B or TN556C ISDN-BRI Line circuit pack or the TN2198 ISDN BRI (U-LT) Line circuit pack (for the network side of the BRI interface). The TN2464 circuit supports T1 and E1 digital facilities.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 739 ISDN trunk group 17 ISDN-PRI interfaces are supported by the TN767 circuit pack (for assignment of a T1 signaling link and up to 24 ISDN-PRI trunk group members), or the TN464C or later circuit pack (for assignment of a T1 or E1 signaling link and up to 24 or 31 ISDN-PRI trunk group members, respectively). The TN2464 and TN2207 circuit pack can also be used with ISDN-PRI. nFor R7si and later configurations and R7csi and later configurations, the D-channel for ISDN-PRI interfaces switches through either the TN765 Processor Interface (PI) circuit pack or the TN778 Packet Control (PACCON) circuit pack. The D-channel for ISDN-BRI interfaces only switches through the TN778 Packet Control (PACCON) circuit pack. NOTE: You cannot use the TN765 circuit pack with ISDN-BRI interfaces. nFor R7r and later configurations, the D-channel switches through the TN1655 Packet Interface (PKTINT) circuit pack. nA TN780 or TN2182 Tone Clock circuit pack provides synchronization for the DS1 circuit pack. NOTE: The TN767 cannot be used to carry the D-channel if either the TN778 (PACCON) or TN1655 (PKTINT) circuit packs are used to switch the D-channel. However, in these circumstances, the TN767 can be used for NFAS interfaces carrying only B-channels.

For Facility Associated Signaling, up to 23 ports are available for administration as trunk members in an associated ISDN-PRI trunk group. The 24th port is used as a signaling channel. For Non-Facility Associated Signaling, all 24 ports may be used on certain DS1 circuit packs. The D-channel signaling function for these packs must be provided by a designated DS1 pack on its 24th channel. — E1 Circuit Pack Assign all fields as required. For Facility Associated Signaling, up to 30 ports are available for administration as trunk members in an associated ISDN-PRI trunk group. Port number 16 is used as a signaling channel. nMaintenance-Related System-Parameters — Use this screen only for a TN778. Set the Packet Bus Maint field to y. nISDN Trunk Group — Enter information in all the fields except the trunk group members. When using ISDN-PRI interfaces, enter the members after you establish the signaling links. nSignaling Group — This screen is required if ISDN-PRI interfaces are used. Complete all fields. This screen identifies groups of ISDN-PRI DS1 interface B-channels for which a given D-channel (or D-channel pair) will carry the associated signaling information (supports the Facility and Non-Facility Associated Signaling feature). Each DS1 board that is required to have a D-channel must be in a different signaling group by itself (unless D-channel backup is needed, in which case a second DS1 is administered as a backup D-channel). You are not required to select a channel for a trunk group, but if you do, you must have already defined the trunk group as type ISDN. NOTE: The following three screens, Processor Interface Data Module, Communication Interface Links, and Communication Processor Channel Assignment are used only to support the ISDN-PRI interfaces using PI TN765.

Design Considerations
ISDN-BRI and ISDN-PRI interfaces cannot be mixed in the same trunk group.
Therefore, consider the following:
nThe earliest trunk member (the lowest numbered one) administered is
considered correct.
nIf an offending member is subsequently found (meaning the first member
was BRI and a later member was PRI, or vice versa), the cursor positions
on the offending member, and the following error message appears:
Cannot mix BRI and PRI ports in the same trunk group.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 746 ISDN trunk group 17 Calling Number – Delete Calling Number – Insert Calling Number – Numbering Format This field indicates the TON/NPI encoding applied to CPN information modified by the CLI Prefix feature. This encoding does not apply to calls originating locally. The Numbering Format field on page 2 of this screen applies to calls originated from this switch. If this field is blank, DEFINITY ECS passes on the encoding received in the incoming setup message. If the incoming setup message did not contain CPN information and digits are added, the outgoing message will contain these digits. If the Numbering Format field is blank in this case, the value defaults to pub-unk. If the Numbering Format field on page 2 of this screen is also administered as unknown, the trunk group is modified to “unk-unk” encoding of the TON/NPI. Therefore, this field also must contain a value other than unknown. NOTE: The values for this field map to the Type of Numbering (TON) and Numbering Plan Identifier (NPI) values shown below.
