T1 service allows the emulation of different analog lines. You can also order
services, such as Megacom 800, over the channels. The capacity, however, is
limited to voice calls and data calls using a modem. In addition, beginning with
Release 4.0 of the MERLIN LEGEND Communications System, T1 supports
ACCUNET Switched Digital Service (or other circuit-switched data service) at
56-kbps when the T1 channel or T1-Tie trunk is configured as T1 Switched 56.
Release 6.0 and later systems allow T1 service to provide PRI or T1 Tie service in
a private network.

service, proceed to the “Tie Trunks” section after completing these instructions. If
you are planning to use T1 service as PRI trunks in a private network, check the
