For the communication between DtermIPs, the voice data is transmitted and received
directly, without converting voice packets into PCM and voice compression in the
system.

-
The System-based DRS executes DtermIP registration.

2.7 Public Network/TIE Network Connection
The system can be connected with a Public Network or Tie Line Network. When the
DtermIP communicates with the DtermIP/Legacy terminal in the destination office via
Public Network or Tie Line Network, IP-PAD cards and trunk cards are required to
transmit and receive the voice data.
-
For the DtermIP communication between offices, the IP-PAD card is required.
-
Peer-to-Peer connection is not available in this connection.
2.7.1 CCIS Connection
The system can be connected in an IP network by No. 7 Common Channel Inter-office
Signaling (CCIS) via the Virtual IPT to other 2000 IPS systems, and to 2400 IPX, iS3000
or SV7000.
For DtermIP-to-DtermIP connection via CCIS (Peer-to-Peer connection), the voice data is
transmitted and received directly between DtermIPs via the IP network (CCIS via IP).
For DtermIP-to-Legacy terminal connection via CCIS, the IP-PAD card is required to
transmit and receive the voice data. This card is used to control and convert the voice
data. The MP card has a built-in Virtual IPT and the Virtual IPT manages control signals
in both types of connections.
-
Peer-to-Peer connection between DtermIPs via CCIS is available only when the
destination office is 2000 IPS, 2400 IPX or SV7000.
-
The Virtual IPT can be connected to a maximum of 127 trunks.
-
The Virtual IPT provides only Point-to-Multipoint connection.
-
When a call over Peer-to-Peer connection via CCIS is put on hold and then answered
at the same station, Elapsed Time Display returns to 0:00:00.
-
When the destination office uses the physical IPT card, for example, when connecting
to the former PBX system, the IPT card and 4VCT card are required in both offices.
-
