Cisco Serial Connectivity Network Modules
Synchronous Serial Network Modules—Up to 8 Mbps
Product Description
NM-4T
Provides four synchronous
serial interfaces, and
Four-port Serial Network
supports a total full-duplex
Module
throughput of 8 Mbps,
which can be realized over
one port (at 8 Mbps) or
across all four ports (at 2
Mbps on each port) . Each
port supports full-duplex
operation at T1 and E1
speeds . All ports use
identical DB-60 connectors
that support five interface
types (RS-232, RS-449,
RS-530, V .35, X .21) in either
DTE or DCE mode .

Asynchronous Serial Network Modules—Up to 128 Kbps
Product Description
NM-16A/S
The NM-16A/S combines
the rich multiprotocol
16-port Asynchronous/
support of the NM-4A/S
Synchronous Serial
and NM-8A/S with higher
Network Module
densities to provide
compelling price-per-port
solutions for networking
applications . In addition to
the features of the
NM-4A/S and NM-8A/S,
the NM-16A/S adds
EIA-530A support, and
support for physical
lead manipulation in the
IOS configuration . Lead
manipulation allows the
user to configure the router
to ignore input signals,
view the state of input
signals, and to monitor the
transitions of input signals .

NM-16A
Provides 16 asynchronous
serial interfaces at speeds
16-port Asynchronous
up to 134 Kbps . The 16
Network Module
ports are cabled with two
custom "octopus" cables,
each terminating in eight
ports, each with an option
of physical endpoints,
including RJ-45 and DB-25
connectors .

IOS Versions Comments
3800 Series–12 .3(11)T In order to achieve higher
port density, the
2811, 2821, and
NM-16A/S uses the Smart
2851–12 .3(8)T4
Serial connector that is
also used on the WIC-2T
WAN Interface Card . Thus
customers must order
Smart Serial cables for
use with the NM-16A/S
instead of the 5-in-1 cables
used on the NM-4A/S and
NM-8A/S .
