Criteria
APPLICATION
Multiplexing
Digital sharing
FEP port sharing
Digital bridge
Provides time division multiplexing of up to two or six independent
ports, depending upon the version, 2-port or 6-port.
Allows two groups of consecutive ports to share the same TDM
channel.
Provides up to three separate FEP port-sharing groups.
Configured to perform a 5-port digital bridge capability.

1.2, 2.0, 2.4, 4.0, 4.4, 4.8, 7.2, 8.4, 9.2, 9.6, 12.0, 14.4, 16.8, 18.0, 18.8,
19.2, 28.8, 32, 38.4, 48, 56, and 64 kbps
PORT ASYNCHRONOUS RATES
150, 300, 600, 1200, and 1800 bps plus all primary (DSU) rates.
Asynchronous rates s2.3, –2.5 percent overspeed/underspeed
compensation.

Provides an additional 25-pin D-subminiature connector, for a total of
two EIA-232 or V.35 interfaces that can be set independently of each
other when you have DSU firmware Release 6.28 or greater.
Provides five additional 25-pin D-subminiature connectors, for a total of
six EIA-232 or V.35 interfaces that can be set independently of each
other when you have DSU firmware Release 6.28 or greater.
Provides a 6-port connector module that provides a total of six 25-pin
D-subminiature EIA-232 connections (including the DSU). In addition, a
26-pin high-density D-type connector provides a V.35 interface through
an adapter cable.
Provides five additional 25-pin D-subminiature connectors that can be
optioned for EIA-232 or V.35, for a total of six EIA-232 or six V.35
interfaces.
Provides one 60-pin high-density D-type connector that provides five
additional EIA-232 interfaces through an adapter cable.
NMS SUPPORT
TDM capability is fully supported by the COMSPHERE 6700 or
6800 Series NMS, Release 4.0 or greater for the 6700 Series NMS and
Release 4.1.5 or greater for the 6800 Series NMS software in ADp and
DATAPHONE
