The 8-port T1/E1 PSTN interface module (WS-X6608-T1/E1) is a high-density,
8-port T1/E1 voice-over-IP (VoIP) module that can support digital T1/E1
connectivity to the Public Switched Telephone Network (PSTN) or transcoding
and conferencing. (See
registered with Cisco CallManager in its domain, and is managed by Cisco
CallManager.
The module software is downloaded from a TFTP server. Depending upon which
software you download, the ports can serve as T1/E1 interfaces or support
transcoding and conferencing as follows:
Transcoding for IP-to-IP connections support the following:
•
128 channels of full-duplex transcoding per module, 16 channels per
–
port, if transcoding is between G.711 and a low bit-rate codec (such as
the G.723.1).
64 channels of full-duplex transcoding per module, 8 channels per port,
–
if transcoding is from a low bit-rate codec to a low bit-rate codec (such
as from G723.1 to G.729).
– G.711, G.723.1, and the G.729A codecs in any combination.
Conferencing supports the following:
•
Meet-Me and ad-hoc conferencing.
–
32 channels of conferencing ports, 4 conferencings per port. The
–
maximum conference size on a single port is 16 parties; 6 parties at a time
can be active (talking) while the rest are idle (listening).
Transcoding and conferencing functions; for every transcoding port in
–
use, one less conferencing port is available and vice versa.
To configure the module interfaces, refer to the "Configuring a VoIP Network"
chapter of the Catalyst 6500 Series Switch Software Configuration Guide. To
configure the interfaces to work with Cisco CallManager, refer to the Cisco
CallManager Administration Guide.
When the 8-port T1/E1 PSTN interface module powers up, it initializes various
hardware components and communicates with the supervisor engine.
