The 2784 NAU provides integrated voice support by
presenting up to 24 voice/fax calls onto the T1 DSX-1 Drop-
and-Insert port. The user may select the number of channels
(1-24 voice/fax calls) to be "dropped" onto the PABX port by
customizing the DS0 channel selection configuration through
the SNMP/HTTP NMS (see screen snapshot, opposite).
DS0s can also be identified as dial-in modem ports. With this
facility, the 2784 will intercept and answer V.90, K56Flex™,
V.34+ and ISDN BRI users via built-in DSP modems.
This allows the 2784 to minimize costs and maximize
facilities by answering remote access calls within the 2784,
while switching calls to the PABX to handle corporate
voice–all at the same time. Now users can call the corporate
voice and data networks, using different telephone numbers
on the same T1.
The 2784 NAU offers a flexible and cost-effective network
access solution using Frame Relay over a multi-service
T1/E1 connection. Designed to be simple and efficient,
Frame Relay is a data networking technology for connecting
remote offices over the Wide Area. While eliminating the
need for individual and expensive leased lines, Frame Relay
provides distance insensitive connections to remote
networks. Connectivity is established through logical end-to-
end connections [Permanent Virtual Circuits (PVCs)]
between the 2784 and the remote office.
Frame Relay provides multiple PVCs over a single physical
circuit, which allows the 2784 to forward data over those
connections to its intended destinations. Using RFC-1490
multiprotocol encapsulation and the 2784's sub-interface
architecture, each virtual circuit is multiplexed over a single
physical interface. The 2784 NAU scales to support
additional connections without adding to capital equipment
costs.
By combining the capabilities of a CSU/DSU, FRAD and
router, the 2784 provides scalability without the additional
costs of multiple pieces of equipment.
