Re: Ethernet Switching Network Module vs HWIC

The NM-1HSSI is a single port, high-speed network module that provides connectivity to a Wide Area Network. Demand for high capacity corporate backbones, high-speed Internet access, Virtual Private Networks (VPNs), and trunking connections for service provider internetworking has led to an increase demand for clear channel DS3 and E3 connections. Also see the NM-1T3/E3 clear channel T3/E3 Network Module

The NM-4T serial network module has four synchronous serial interfaces. The network module supports a total full-duplex throughput of 8 megabits per second (Mbps), which can be realized over one port (at 8 Mbps) or across all four ports (at 2 Mbps on each port).

You should checkpout following link.

I am focusing on TABLE-6.

Re: Ethernet Switching Network Module vs HWIC

Hi Eric,

The latest NM slot type is NME, it has 1Gbps speed connecting to backplane. http://www.cisco.com/en/US/products/ps5855/products_qanda_item0900aecd8028d16a.shtml

For HWIC, I can find that HWIC-4ESW support upto 100Mbps in total while HWIC-9ESW supports upto 200Mbps in total.

In general NM supports a variety of network module like Unity Express, WLC module, network analysis module etc.

Tks

Leon
