ISDN Features

Primary Rate Interface (PRI), Answering Calls

Programming (Cont’d)

35-02-16 : SMDR Output Options, Trunk Name or Received Dialed Number

If SMDR is used, this option allows you to determine how the SMDR should print incoming calls on ANI/DNIS or DID trunks (0=print trunk port name assigned in Program 14-01-01, 1=print received dialed number). On ANI/DNIS trunks, if enabled, the DNIS digits can be printed instead of the trunk name. If a call is received on a DID trunk, the received number can be printed. If the received number is not in the DID Translation Table (Program 22-11-01), then no number is printed. On ISDN trunks, the called party number can be printed for DID’s, if desired.

Default Setting: Print Trunk Port Name (0).

82-01-01 : Incoming Ring Tone

Customize the incoming ring tone (the tones a user hears when a call rings an extension). Trunks ring extensions according to the Ring Tone Range selected in 22-03-01 and the user settings made with Ser- vice Code 820.

Default Setting: Refer to Program 82-01-01 in the Software Manual.

Related Features

Direct Inward Dialing

Use DID to control the inbound routing of PRI trunks. With DID, the system will use the last three or four digits of the Called Number Information Element to route an incoming call via the DID translation tables. When programming PRI lines for DID, refer to the Aspire Software Manual (P/N 0893200) for further programming information.

Forced Trunk Disconnect

This feature only works on analog trunk. ISDN trunks do not have the Forced Trunk Disconnect available.

Night Service

If enabled, an extension user can dial the Universal Answer code to pick up a ringing PRI trunk.

Transfer

Transferred calls on DISA, DID, ISDN trunks, or from the VRS can display the reason a call is being transferred (Call Forward, Busy, No Answer, or DND).

Operation

To answer an incoming trunk call:

1.Lift handset.

2.At keyset, press flashing line key.

If you don’t have a line or loop key for a PRI call ringing your phone, it rings an idle CALL key. If you have Ringing Line Preference, lifting the handset answers the call.
