T1 Service
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 tandem PRI service in
a private network.
The planning form instructions below apply to both T1 and T1 Switched 56 service
except where noted. If you are configuring channels for T1 Switched 56 service,
complete these instructions then proceed to the
section that immediately follows. If configuring T1-Tie trunks for T1 Switched 56
service, proceed to the
you are planning to use T1 service as PRI trunks in a private network, check the
PRI box under Type of Service on Form 3b (page 1). See the Network Reference
for more information regarding configuration for use in a private network.

lowest-numbered slot, and the last box for the highest-numbered
slot.
NOTES:
For T1 or T1 Switched 56 service, the T1 box must be checked
on the form. (If you leave this blank, and T1 is not specified
during programming, the 100D module will not be programmed.)
