Centralized Automated Message Accounting Trunk Protocol
Interface Cards
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
Note
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.
