We have an office with a SX2000 that is overtrunked and the powers to be wants to disconnect the T1. I have routed all outgoing calls away from it to another trunk group and now I am in a holding pattern for them to move the TF numbers coming in on it. My question is how to dismantle the programming...my first step would be to busy out the trunk and then delete the members in the Trunk Group Assignments and then the same in Trunk Assignments. It also has a digital link assignment and I just noticed that under the Network Synchronization form it is being used as the first clock source. When this T1 is removed, the office will be using LS/GS lines - if that is the case, does the PBX need a clocking source or can it use its own internal clock? Any suggestions? Thanks.
