Data compression
Business Communications Manager provides a WAN Data Compression feature.
On the UTWAN connection, Business Communications Manager supports the following data
compression protocols:
•
Frame Relay Forum standard FRF.9 data compression protocol with STAC compression
algorithm
•
PPP Compression Control Protocol (RFC 1962) with STAC compression algorithm
Configuring the Business Communications Manager to use the
UTWAN
The UTWAN interface allows circuit-switched voice traffic and packet-switched data traffic
(including IP Telephony) to use the same physical link. This requires you to assign some of the T1
lines for voice traffic and some of the lines for data traffic. After you have assigned the lines, you
must configure UTWAN link layer parameters for data traffic.

"Configuring the UTWAN Network Interface parameters" on page 175
Note: Only one DTM can be used for UT1 connection.
Of the 24 available T1 lines, the maximum number of lines that can be assigned for data
traffic is 16.
Assigning lines for voice traffic
A digital T1 line has up to 24 telephone lines available for use. When using the UTWAN feature,
you can assign some of these lines to telephony traffic and some to data traffic. For the lines that
you want to use for telephony traffic, configure the lines in the same manner as you configure
other telephony lines. For information about how to configure digital lines, refer to
lines (PRI, T1, DASS2)" on page
152.
