Network Modules
This section provides information about the following network modules for Cisco modular routers:
•
•
•
Note The Cisco NM-16A/S network module uses a Cisco patented 12-in-1 Smart Serial cable.
With the appropriate serial transition cable, the ports on these modules can provide an EIA/TIA-232,
EIA/TIA-449, V.35, X.21, EIA/TIA-530 DTE, or NRZ/NRZI serial interface. The NM-16 A/S network
module can provide an EIA/TIA-530A DTE interface.
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
Caution
connect the 8-port A/S serial network modules (NM-8A/S) and 16-port A/S serial network modules
(NM-16A/S) only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be
shielded and the shield must be grounded at both ends.
