VComp Bundle Overview
Voice compression (VComp) bundles compress
and aggregate voice channels going between the same IP endpoints into
a single IP flow.
Figure 1 shows
the common voice architecture and key components of the CTP Series.
Figure 1: CTP Series Voice Architecture and Key Components
As shown
in Figure 1, VComp
bundles support the following applications:
- PBX interconnect—The 4W-E&M interfaces enable
CTP devices to connect directly to analog PBX voice switch trunks
and interconnect those trunks over the IP/MPLS network. Interworking
between 4W-E&M and T1 or E1 DS0s enables small analog sites to
be aggregated into larger digital T1 or E1 PBX voice switches.
- PBX extension—The 2W-FXS and 2W-FXO interfaces enable
CTP devices to connect directly to two-wire analog PBX voice switch
interfaces to extend the phone extension over the IP/MPLS network.
Interworking between 2W-FXS and 2W-FXO to T1 or E1 DS0s enables small
analog sites to be aggregated into larger digital T1 or E1 PBX voice
switches.
