Features
Primary Rate Interface (PRI) and T1
Incoming Calls
PRI
When an incoming call is given routing-by-dial-plan treatment, the green LED
associated with the appearance of the line lights steadily; the LED does not flash
to indicate that the line/trunk is ringing. When an incoming call is on a personal
line, the green LED associated with the line lights steadily, and ringing on an SA
button occurs. The LED does not flash to indicate that the line/trunk is ringing.
Routing by dial plan requires programming of the Dial-Plan Routing Table and of
the B-channel group (PRI only) or extension to be routed by dial plan.
Call Management System (CMS) does not support routing by dial plan.
Routing by dial plan information appears only on MLX display telephones.
If the number for an incoming call given routing by dial-plan treatment is not found,
the call is sent to the invalid number destination for DID calls. This can be a dial-
plan extension number or fast busy tone. However, if it is fast busy tone, the call is
rejected and the network applies intercept tone.
A PRI line that has been programmed for routing by dial plan should not be
programmed for remote access or Shared System Access.
Outgoing Calls
PRI
When placing a call using a PRI facility, you may want to append a
number. This signals the facility that the number is complete and causes the call
to be placed immediately.
The outgoing telephone number that matches the digit pattern in the Network
Selection Table is deleted automatically. This is not programmable. The common
carrier ID is sent to the foreign exchange.
In systems that are programmed using a non-uniform extension dialing plan, one
base number may not be able to represent all telephones.
To specify that no telephone number is sent to the network, choose the Do Not
Copy Telephone Number programming option and use the Telephone Number to
Send procedure to ensure that telephone numbers are not assigned to each
channel in the B-channel group. A network option to block presentation of CPN is
also available.
If ARS identifies a call as applying to a call-by-call B-channel group but the
Call-by-Call Services Table does not show a matching digit pattern and bearer
capability, the call is rejected.
