SmartSwitch 1800 Voice Configuration

About SmartSwitch 1800 voice support; configuring system-level voice parameters; speed-dial

configuration; configuring voice ports and voice interfaces; viewing voice statistics

The two voice ports in the SmartSwitch 1800 provide connectivity over frame
relay for telephones, PBXs (Private Branch Exchange), fax machines, and analog
modems.
Calls are routed between voice ports and frame relay ports by internal mapping
(using a dial table) that reads the destination node number for a voice call and
associates it with a voice interface. The voice interface record includes an
associated frame relay port and DLCI over which the Call Request frame will be
sent to the destination node.
The SmartSwitch 1800 can combine voice and data frames over the same frame
relay DLCI. With the current version of Þrmware, splitting the voice and data at
the other end requires a connection to another Cabletron frame relay device (FRX
or SmartSwitch 1800). That device must be conÞgured with a PVC between the
network frame relay port and the frame relay port that will transmit only the
voice frames. (Once the data and voice frames have been separated in the
Cabletron frame relay device, each data frame will be routed based on the DLCI
conÞguration and data type.)
NOTE
At the time of this SPMA release, the SmartSwitch 1800 supports the collection of voice
port statistics, but does not allow the actual conÞguration of voice ports or voice
interfaces. Full voice support will be included in a future release of SPMA.
You can conÞgure voice ports and voice interfaces through console management. Refer to
your SmartSwitch 1800 hardware documentation for more information.
