Document Revision 1
Conditions
r The DISA caller must use an analog type (DTMF) telephone. DISA is compatible with
calling devices that meet the DTMF signaling requirements of EIA Specification RS-464.
DISA trunks must be ground start or supervised loop start.
The Continue/Disconnect code must be DTMF.
r
r With an analog trunk, the Continue/Disconnect code may work using DTMF sounds from
the opposite side trunk. With an ISDN trunk, Program 14-01-25 must be enabled to detect
the Continue/Disconnect code.
r The Continue/Disconnect code is not accepted while dialing a trunk.
r Continue/Disconnect codes will not work if all DTMF receivers are busy.
When used with the Networking feature, both systems must be programmed the same.
r
r In a system with ARS enabled:
When a DISA caller dials 9 for an outside call (if allowed), the system routes the call via
ARS.
r In a system with ARS disabled:
When a DISA caller dials 9 for an outside call (if allowed), the system uses the routes
programmed for Trunk Group Routing.
r Transferred calls on DISA, DID, DIL, ISDN trunks, or from the VRS can display the reason
a call is being transferred (Call Forward, Busy, No Answer or DND).
r Long conversation cutoff is controlled separately for manually transferred Tandem Trunk
calls, automatically transferred Tandem Trunk calls, and DISA calls.
r Tandem Trunking also uses the Continue/Disconnect codes DISA uses.
r Department Calling with Overflow Message requires a DSP daughter board for VRS.
