Direct Inward System Access (DISA)
The Direct Inward System Access (DISA) feature allows you to call into the Panther II
system from a telephone located outside the office and--
* place calls using Panther II system C.O. lines, or
l
make internal calls directly to Panther stations.
You are most likely to use DISA to make work-related, long-distance calls from your
home phone, from a local telephone in a client' s office, or from a pay phone, during or
after normal working hours. The advantage of using DISA is that you' re making your
long-distance call on one of the Panther system C.O. lines, so the call will be billed to
your office and not to the telephone that you' re calling from.
You can also use DISA to place an internal call directly to a station in the office. This
saves you from having to go through the Master Attendant to call a station.
Two amplified lines are required to place an external call using DISA, but amplified lines
aren' t required to place a DISA call to a station in the office. So, you can be using DISA
to call a station and there will still be four amplified lines available for Trunk to Trunk
Conferences, External Call Forwarding or for making external calls using DISA. How-
ever, if all four of the system' s amplified lines are being used when you try to access the
system on the DISA line, you will hear continuous ringing and must try again later.
Programming
Any two C.O. lines may be programmed as incoming DISA lines. The only exception to
this rule is that you can' t program an incoming ECF line as a DISA line.
Once you' ve accessed the system using DISA, you can call any station, or use any C.O.
line to make an external outgoing call. However, before you can access the system, you
must enter a 4-digit DISA access code. Since there is no default value for this code, you
must program at least one DISA access code. Up to four DISA access codes can be pro-
grammed for the system.
