PARTNER Advanced Communications System Installation, Programming, and Use

The T1 Module

The T1 module provides up to 16 lines, even though
it contains only one line jack.
The T1 module provides 24 channels, but a
maximum of 16 channels can be used for voice
lines. (Channels 9 through 24 are used for voice.)
These channels can be assigned to line or pool
buttons and used for incoming and outgoing calls.
The eight unused (that is, unequipped) channels
(channels 1 through 8), and any channels you do
not use for voice lines, can be used for data
connectivity by placing an external Channel Service
Unit (CSU)/DSU (Data Service Unit) between the T1
module and your T1 service provider.
The T1 module also provides Direct Inward Dialing
(DID) capabilities, allowing calls to be routed
automatically to particular extensions, hunt groups,
and calling groups based on the digits received from
the T1 service provider. With DID, a caller can dial a
PARTNER extension directly, without the assistance
of an attendant. Note that you can make outgoing
calls on T1 lines with DID. You must contact your T1
service provider for DID.
The T1 module contains:
one RJ-45 port to connect your service provider
to the T1 module
three pairs of bantam jacks (labeled Transmit,
Receive, and Monitor) for maintenance testing
and diagnostics
an internal CSU for voice call connectivity to the
T1 service provider and diagnostics (see
Figure 2-21)
To configure and maintain a T1 module, you must
use the PARTNER ACS R7.0 PC Administration
software. You cannot program a T1 module via
System Programming from extensions 10 or 11.
