T1 Trunking (with ANI/DNIS Compatibility)
538 ◆ Features Aspire Software Manual
Conditions
(A.) T1 Trunking requires a T1/PRI Interface PCB and a customer-provided CSU/DSU to interface
with the telco. Consult your sales representative and the system Hardware Manual for addi-
tional details.
(B.) ANI/DNIS Compatibility requires the use of system DTMF receivers. When all receivers are
busy, the incoming ANI/DNIS call waits for a receiver to become available.
(C.) The ANI/DNIS/Address data received from the telco can be up to 10 digits long.
(D.) When connecting to T1 trunks, after changing Program 22-02-01 to match the telco’s con-
nected T1 service type, the T1 cable or the T1 PCB must be unplugged and then reconnected
in order for the T1 PCB to sync.
(E.) The Aspire S does not have T1 trunking ability.
Default Setting
Disabled.

- In heavy traffic sites, allocate one DTMF receiver for every 5 devices that use them.
➻ 14-01-02 : Basic Trunk Data Setup - Transmit CODEC Gain Type
14-01-03 : Basic Trunk Data Setup - Receive CODEC Gain Type
Assign a CODEC Gain Type to each trunk. This sets the amount of gain (amplification) for the
selected trunk.
➻ 14-01-07 : Basic Trunk Data Setup, Outgoing Calls
For ANI/DNIS, the following additional setting is recommended: Outgoing Calls = 1 (Allowed)

● Item 2: Ring Detect Type = 1 (Immediate)
● Item 3: Flash Type = 0 (Open Loop Flash)
● Item 4: Flash for Time Flash or Disconnect = 0 (Timed Flash)
● Item 5: Dial Tone Detection for Manually Dialed Calls = 1 (Outgoing calls allowed)
➻ 14-02-02 : Analog Trunk Data Setup - Ring Detect Type
