Cisco Cisco VN 2900 Network Adaptation Interface Guía De Instalación

Check that the CD LED comes on, which means that the card’s internal DSU/CSU is communicating 
with the DSU/CSU at the T1 or E1 service provider central office.

The Centralized Automated Message Accounting (CAMA) trunk protocol interface connects local calls 
to emergency services. The CAMA card provides the software features required to connect directly to 
the enhanced 911 (E911) network from the customer premises. It also provides direct connections to a 
Public Service Answering Point (PSAP) using analog CAMA trunks. The CAMA protocol provides 
in-band signaling.

For the NM-HD-1V, NM-HD-2V, and NM-HD-2VE voice network modules, and for the Cisco 1751 and 
1760 routers, CAMA is supported by the VIC2-2FXO interface card. The VIC-2CAMA card cannot be 
used with the NM-HD-1V, NM-HD-2V, or NM-HD-2VE voice network modules, or with the Cisco 1751 
or Cisco 1760 routers.

The 2-port CAMA card is illustrated in

Use a straight-through RJ-11 cable to connect the VIC-2CAMA voice interface card to the PSTN or PBX 
through a telephone wall outlet. 

Ports on this interface card are colored pink. 

Confirm that the router is still turned off.

Connect one end of the straight-through RJ-11 cable to an RJ-11 port on the card. (See
