T1 Trunks (with ANI/DNIS Compatibility)
The T1/PRI Interface ETU gives the system T1 trunking capability. This ETU uses a
single universal slot and provides up to 24 trunk circuits. In additional to providing
digital-quality trunking, the T1/PRI Interface ETU allows you to have maximum
trunking capability with fewer ETUs. This in turn makes more universal slots available
for other functions.
You can program each T1/PRI ETU for any combination of the following trunks:
J
CO loop start
J
CO ground start
J
Direct Inward Dialing
J
Tie lines
1
The T1/PRI Interface ETU uses the first block of 24 consecutive trunks. For example,
if you have an 8COIU ETU installed for trunks 1-8, the T1/PRI Interface ETU will
automatically use trunks 9~32. If you have 8COIU ETUs installed for trunks 1~8 and
17~24, the T1/PRI ETU will use 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 ETU requires that 24 consecutive ports be available in the
system even if not all the ports will be used otherwise the ETU will not function.
ANI/DNIS Compatibility
The system is compatible with Telco’s T1 Automatic Number Identification (ANI) and
Dialed Number Information Service (DNIS) services. A compliment to Caller ID
service, ANI/DNIS Compatibility provides:
J
Selectable Receive Format
You can set up the system for compatibility with any combination of ANI, DNIS
and Dialed Number (Address) data provided by the Telco.
J
Flexible Routing
Based on the data received, the system can route the incoming ANI/DNIS call
to:
N
An extension
N
An ACD or Voice Mail master extension number
N
A VRS and play a VRS message to the caller
N
A Department Group pilot number
N
A trunk Ring Group
1. Two-wire (four-lead) type 1 tie lines (FIC TL11M) only.
