TXDISC TIMER
The Timer (bothway) Disconnect setting defines the duration of time necessary for sending
the disconnect indication prior to disconnecting the call. The values (in milliseconds) are
1000, 2000, 3000 and 4000. This timer is used for mode1 calls.
TCID TIMER
The Timer Channel Identifier setting defines the duration of time spent by the network looking
for secondary B channel allocation information before disconnecting the call. The values (in
milliseconds) are 1000, 2000, 3000 and 4000. This timer is used for mode2 and mode3 calls
(when available).
TANULL TIMER
The Timer (answer) Null State setting defines the duration of time spent by the called user
looking for bonding information before disconnecting the call. The values (in milliseconds)
are 5000, 2500, 7500 and 10000. This timer is used for mode0 and mode1 calls.
TXDEQ TIMER
The Timer (bothway) Delay Equalization setting defines the duration of time given the called
user to complete equalization of the call. The values (in milliseconds) are 20000, 10000,
30000 and 50000. This timer is used for mode1 calls.
TXFA TIMER
The Timer (bothway) Frame Alignment setting defines the duration of time (per channel) for
the called user needs to find frame alignment. The values (in milliseconds) are 20000, 10000,
30000 and 40000. This timer is used for mode1 calls.
1.3.8 Dialing with High Speed Data Cards
All models of HSU cards can place outgoing calls and can receive incoming calls.
All outgoing calls use call profile information to dial (see HSU Call Profile section earlier in
this chapter). A call profile is loaded into an HSU port’s dialing memory using the “D” (Dial)
option from the HSU Card Screen.
All incoming calls are routed to HSU ports based on the primary and hunt (optional) group
phone number(s) assigned to the HSU port. These numbers are assigned to each HSU port
using the Dial command option from the HSU Card Screen.
