UNIVERGE SV8100 Issue 5.0
General Description Manual 2 - 69
The DT700 series telephones provide a converged infrastructure at the desktop, with
a 10Base-T/100Base-TX connection to the LAN and built-in hub for a PC connection
to the telephone itself. The system can provide peer-to-peer connections between the
DT700 series telephones with voice compression, offering existing IP telephone
features with an enhanced user interface. On the WAN side, the system can provide
peer-to-peer connections over IP networks with the voice compression, on CCIS over
IP or Remote Unit over IP.
 Remote Unit over IP is available only for the SV8300.
The SV8100/SV8300 can provide legacy line/trunk interfaces to support the existing
Time Division Multiplexing (TDM) based infrastructure, such as analog telephones,
digital telephones (DT300 series), analog networks and digital networks (T1/E1,
ISDN, etc.).
Synchronous Ringing
Synchronous Ringing synchronizes CO/PBX incoming ringing with the incoming
ringing pattern from a
Central Office.
T1 Trunking (with ANI/DNIS Compatibility)
The T1/PRI Interface gives the system T1 trunking ability. This blade uses a single
universal slot and provides up to 24 trunk circuits. In additional to providing
digital-quality trunking, the T1/PRI Interface allows you to have maximum trunking
ability with fewer blades. This in turn makes more universal slots available for other
functions.
You can program each T1/PRI for any combination of the following trunks:

CO loop start

CO ground start

Direct Inward Dialing

Tie lines [Two-wire (four-lead) type 1 tie lines (FIC TL11M) only].
The CD-PRTA blade uses the first block of 24 consecutive trunks. For example, if you
have CD-4COTB with PZ-4COTF installed for trunks 1~8, the T1/PRI Interface
automatically uses trunks 9~32. If you have CD-4COTB with PZ-4COTF installed for
trunks 1~8 and 17~24, the T1/PRI uses trunks 25~48. The T1/PRI Interface cannot
use trunks 9~16 (even if available) since they are not part of a consecutive block of 24
trunks. Each T1/PRI requires that 24 consecutive ports be available in the system
even if not all the ports are used, otherwise the blade does not function.
The CD-PRTA can be programmed as a 4/8/12/16/20/24 port Fractional T1PRI.
