4-Port Serial Interface Network Modules (NM-CEM-4SER)
The 4-port serial interface network module (NM-CEM-4SER) is a single-wide CEoIP network module
with four serial ports that support the following interfaces:
•
EIA/TIA-232
•
EIA/TIA-449
•
EIA-530
•
EIA-530A
•
V.35
•
X.21
Caution
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the 4-port serial interface network module (NM-CEM-4SER) only to intrabuilding or
nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded
at both ends.
The interface type provided by the port is determined by the cable connected to the port. For information
on interface-specific cabling requirements, see the
“Connecting 4-Port Serial Interface Network
Modules to the Network” section on page 27-3
.
For information on network module LEDs, see the
“4-Port Serial Interface Network Module
(NM-CEM-4SER) LEDs” section on page 27-3
