Cable Requirements - Avaya Nortel Communication Server 1000 Reference

Total_Num_DCH-Units = Num_DCHx1 + Num_DDCHx2 + Num_MSDLx4
Therefore, Total_Num_DCH-Units in any given system is between 0-63.
CPU capacity
Using a NT5D97 DDP2 card instead of DTI2/PRI2 cards does not increase the load on the
CPU. The DDP2 replaces an ENET card and two DTI2/PRI2 cards. Emulating the ENET card
and the overall CPU capacity is not impacted by using a DDP2 card instead of a DTI2/PRI2
card.

Cable requirements

This section lists the types of cable used and the lengths required for internal and external
NT5D97 DDP2 connections.
Note:
No additional cabling is required for nB+D configurations. Multiple DDP2 cards and the D-
channel are associated through software in LD 17.
DDP2 cable assemblies include:
• E1 carrier cables
- NTCK45AA (A0407956)
- NT8D7217 (A0617192)
- NTCK78AA (A0618294)
