Table 19

identifies the IISDN_R2_INTERREGISTER_PARAMS

sub-structure containing the parameters required used to configure

the MFC inter-register signaling.

c_d_cas_bits

Specification of the CAS C

bit and D bit settings.

0: CD=00
1: CD=01
2: CD=10
3: CD=11

ClearbackControl

Used by the outbound side

to determine whether the

network will use a release

guard (AB=11) or a forced

release (AB=00) signal to

tear down a call, The

selected signal is handled

accordingly, while the

other is simply ignored.

0: release guard
1: forced release

The Following Parameters Can Be Modified According to Application Requirements:

dnisMaxNumDigits

Maximum number of DNIS digits

required.

[0-IISDN_MAX_

DIGITS]

aniMaxNumDigits

Maximum number of ANI digits

required.

[0-IISDN_MAX_

DIGITS]

dnisNumDigitsBeforeANI

The number of DNIS digits to

collect before requesting ANI.

[1...N], where N =

dnisMinNumDigits

interForwardToneTimeOut

Period associated with the inbound

channel “T3” timer that supervises

the interval elapsing between

recognition of two consecutive

forward tones. (Ref. ITU Q.476).

Seconds Typically, set to [8-24],

but refer to network

specification.

prePulseToneDelay

The interval from the end of the

last backward signal and the start

of a backward pulse signal

(Ref. ITU Q.442).

Set to >= 100
