Universal T1 WAN (UTWAN) 169
Programming Operations Guide
Universal T1 WAN (UTWAN)
The UTWAN enables a Business Communications Manager system to use a Universal T1
connection to send and receive voice and data information. By sharing this connection you can
make more efficient use of your digital network resources and reduce the amount of equipment
needed to support your voice and data networks. The UTWAN is currently available only for
North American installations.
Net Link Manager provides continuous WAN connection status monitoring. For information about
Net Link Manager, see
“Configuring Net Link Manager” on page 733 .

Activating the UTWAN feature
The UTWAN functionality, along with RTP Header Compression, PPP Fragmentation and Frame
Relay Fragmentation, are being made available through a controlled release process. This means
that although the UTWAN functionality is installed on the Business Communications Manager,
the UTWAN headings and menu items are not visible on Unified Manager by default.
To make the UTWAN headings and menu items visible on Unified Manager, you need to use a
utility available from Nortel Networks. To obtain this utility, call the Nortel Networks Technical
Support line.
1-800-4NORTEL (1-800-466-7835)
If you already have a PIN Code, you can enter Express Routing Code (ERC) 196#.
If you do not yet have a PIN Code, or for general questions and first line support, you can enter
ERC 338#.
After you use the utility to display the UTWAN heading, you can program the UTWAN features
as described in the UTWAN section of the
Business Communications Manager Programming
Operations Guide .
