Features
Network Services Supported
This option specifies the type of outgoing network service provided by each B-
channel group. The choices are as follows:
■ MEGACOM WATS
■ MEGACOM 800
■ MultiQuest Service
■ ACCUNET Switched Digital Service (SDS)
■ Software Defined Network (SDN)
Copy Telephone Number to Send
This option specifies whether or not the telephone number to send to the
network for outgoing calls made on PRI lines assigned to a B-channel group is
copied from the telephone number assigned to the channel. Select the Copy
Phone Number to Send option when the telephone number sent to the
network should match the number received from the network indicating the
number dialed by the outside caller. Select the “Do not Copy Phone Number”
option when a telephone number to send is assigned to each channel in the B-
channel group or when no telephone number is to be sent to the network.
Telephone Number to Send
This option assigns the telephone number to send to the network when outgoing
calls are made on PRI lines. If the person being called subscribes to the AT&T
INFO2 automatic number identification (ANI) service, the number indicates who
is calling.
Test Telephone Number
This option assigns a test line/trunk telephone number for each 100D (DS1)
module installed in the control unit.
Timers and Counters
This option sets the timer and counter thresholds. The factory settings for
thresholds are standard and rarely need to be changed. (See At a Glance in
this section for factory settings and valid ranges.) When no response is
received from the network before the programmed setting, the communications
system takes the appropriate corrective action. The timers and counters are as
follows:
■ T200 Timer — times the delay in link layer acknowledgment of a message
sent from the communications system to the network over a D-channel
■ T203 Timer — times the period of time between each exchange of
messages between the communications system and the network on the
D-channel
