NOTE)
1) iPECS UCP-100 is equipped with two (2) FXS ports, and one of several built-in CO Line units may
be factory or field installed.
4 analog CO Lines (UCP-COIU4), uses two (2) VoIP DSP channels
2 BRI Lines, 2B+D each, (UCP-BRIU2) , uses two (2) VoIP DSP channels
4 BRI Lines, each 2B+D, (UCP-BRIU4) , uses four (4) VoIP DSP channels
2) Note the built-in PSTN interfaces require dedicated DSP resources. These DSP resources reduce
the maximum VoIP DSP resources available shown in the above chart.
The built-in VoIP Switching channels implement agent and packet relay functions. Remote device
and network interfaces send RTP traffic to the VoIP channel, which forwards traffic to the
appropriate local iPECS device. The VoIP Switching channel also forwards multi-cast packets to
the remote end-points and local non-iPECS devices. Only the g.711 codec is allowed unless there
is an available VoIP DSP channel.
3) The number of VoIP Switching channels can be increased to the maximum with license installation.
4) Approximately 35 minutes (16 Mbytes) of the VSF and UVM memories are used to provide basic
system prompts. The remaining memory can be used for announcements and voice message
storage. Note the built-in VSF supports the g.711 Codec only; the UVM supports g.711, g.729,
g.723, and g.722 Codec.
