Remote Gateway 9150 Installation and Administration Guide
Configuring the Remote Gateway 9150 unit
Standard 4.0
When placing a telephone call, the dial tone is delayed from the time that the
user goes off-hook. The duration of this delay depends on the number of
simultaneous calls actually being set up. With Remote Gateway 9100 Series, the
dial tone delay is equal to the number of appearances, or calls, multiplied by
approximately 300 milliseconds (ms), or 0.30 seconds (s).
Therefore, when placing a call from a Remote Gateway 9100 Series MADN
with 9 appearances, expect a dial tone delay of approximately 2700 ms, or 2.7 s:
9 appearances x 300 ms = 2700 ms
The following table calculates approximate Remote Gateway 9100 Series dial
tone delay for three different scenarios:
Notes:
If you start from an idle state, include time for ISDN line set-up, which can
be as much as an additional 4–6 seconds.
A Remote Gateway 9100 Series MADN with 10 or more appearances is not
supported.
Associating trunk groups with local stations
Each trunk group can be defined to ring only specific stations. This feature
allows you to route certain types of calls (such as incoming calls on a 1-800
number) to specific stations.
MCR keys increase DSP requirements
In determining the DSP requirements of your Remote Gateway 9100 Series
system, your calculations must consider the number of ports containing MCR
keys. The over-riding concept to keep in mind when determining DSP
requirements is that each ringing or answered telephone call requires one DSP
channel.
