Note High-Speed Serial Interface (HSSI) network modules are supported in Cisco 3600
series routers only.
This chapter describes how to connect the 1-port High-Speed Serial Interface (HSSI)
network module (Cisco product number NM-1HSSI) for Cisco modular access routers. It
contains the following sections:
• HSSI Network Module on page 13-1
• Connecting HSSI Modules to the Network on page 13-2
• HSSI Network Module LEDs on page 13-4
HSSI Network Module
The HSSI network module (see Figure 13-1) is capable of sustaining rates up to T3/E3
speed on Cisco 3600 series routers. A single HSSI port supports Asynchronous Transfer
Mode (ATM)/Data Exchange Interface (DXI), Switched Multimegabit Data Service
(SMDS), Frame Relay, or High-Level Data Link Control (HDLC) connectivity options. It
supports speeds up to 52-Mbps full duplex.
