Page 54 MERLIN LEGEND Communications System Release 6.0 Issue 1 Network Reference 555-660-150 February 1998 Introduction Tandem Trunking and Tandem Switching Page 1-12 To ensure proper transmission quality, the path of a network call should include no more than two spans of analog tie trunks.

Page 66 MERLIN LEGEND Communications System Release 6.0 Issue 1 Network Reference 555-660-150 February 1998 Call-Handling Scenarios Networking Guidelines Page 2-6 Automatic Route Selection (ARS) Local system users may use ARS to route calls over tandem trunks to the PSTN facilities connected to a non-local system. This arrangement can provide toll cost savings when users need to reach outside numbers that are not in their own local calling area but are local to other systems in a network.
Page 67 MERLIN LEGEND Communications System Release 6.0 Issue 1 Network Reference 555-660-150 February 1998 Call-Handling Scenarios Networking Guidelines Page 2-7 Programming Remote Access over Tandem Trunks Non-local users who access your PSTN trunks via ARS and private network trunks do not dial a remote-access barrier code. For security purposes, the system applies the default class-of-restriction (COR) calling restrictions that you assign to all tie (T1-emulated voice or data, or analog) or non-tie (PRI) trunks, ignoring the barrier code requirement setting.
Page 68 MERLIN LEGEND Communications System Release 6.0 Issue 1 Network Reference 555-660-150 February 1998 Call-Handling Scenarios Networking Guidelines Page 2-8 measures. When a Remote Access code is included in the non-local dial plan of the calling system, the caller’s barrier code FRL on the called system is compared to the UDP or ARS route FRL on the called system.
Page 69 MERLIN LEGEND Communications System Release 6.0 Issue 1 Network Reference 555-660-150 February 1998 Call-Handling Scenarios Networking Guidelines Page 2-9 With a given network system, all the trunks that connect to another specific switch must have the same identifying switch identifier number. For example, if two T1- emulated tie trunks connect System B to System A, System A’s manager must ensure that both of those tandem tie trunks are labelled with the same switch identifier, which is different from the switch identifier that labels a third trunk...
