Operation
This is especially useful for access to the remote
programming mode through DISA.
To use this feature, the desired phone numbers must
be programmed in the Auto DISA Table as described
in "Caller ID Auto DISA Programming" on page 2-8.
When a CID call is sent to the DBS, the CID number
is checked against the table. If the number is found,
the caller will automatically be connected to DISA
dial tone.
Limitations.
IMPORTANT: This feature requires the Caller
ID information be received in the order Date/
Time, Number and optionally Name.
Timing Interactions. According to network
specifications, Caller ID data is transmitted to
customer premise equipment between the first and
second rings. Network specifications also allow the
duration of the first ring to range between .2 and 2.2
seconds.
As shown in Figure 3-9 below, the DBS begins
collecting Caller ID data approximately 0.03 seconds
after the initial ring ends. With COs using longer
initial ring cycles, the collection period may elapse
before all data is collected. If all the CID data is not
collected or the data does not match a number in the
Caller ID DISA table, the incoming call will not be
treated as a DISA call but will be treated as a regular
incoming trunk call.
