Cisco 32-Port Async Network Interface Module NM 32A for Cisco 2600, 3600, 3700, MWR-1941 Series
The NM-16A and NM-32A network modules provide flexible, high-density asynchronous connectivity at a competitive price per port and higher performance than comparable third-party solutions. The modules support V.34 speeds at up to 4x compression (134.4 kbps) over the asynchronous connection. Three examples where this module can be deployed follow:
• Small to medium-sized power branch offices where remote users require modem dial access; a fully configured Cisco 3845 chassis with four async network modules connected to the modem rack enables connectivity for up to 128 dial-in users
• Medium-sized branch offices that require a high-density terminal server; a fully configured Cisco 3845 chassis with four async network modules connected to the modem rack (with optional custom cables) enables connectivity for up to 128 terminal connections
• Telemetry applications, connecting a NM-32A module to private branch exchange (PBX) serial ports, data collection equipment, or router consoles
Cabling
The NM-16A and NM-32A modules support two or four Cisco "octopus" cables. Each cable terminates eight ports, with optional physical endpoints of RJ-45 or DB-25. A NM-16A module requires two cables, and the NM-32A requires four cables. Table 4 shows the available cables and end connectors for use with the NM-16A and NM-32A.
