Norstar E&M Trunks

The following notes apply to interfacing a Norstar with a Motorola Vanguard 320 VoIP Gateway, but may be adapted for other E&M (tie trunk) applications.

In general

Norstar Programming

Hardware - TrunkMod allows you to configure the Trunk Cartridges in the Trunk Module. Press CHANGE to select the E&M setting.

Note: You cannot change this setting unless you first disable the Trunk Cartridge using Module Status in Maintenance.   Trunk Cartridge slots in the module are numbered from left to right. Remember to enable the Trunk Cartridge when you have completed programming!

Testing:

Verify far-end circuits by activating near-end M lead and listening for far-end dial tone.
Verify near-end circuits by activating near-end E lead and listening for near-end dial tone.
