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
Figure 12-4.) The module requires
an IP address, is 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).
