# MFC-R2 editable parameters

To program the MFC-R2 TCP to operate within different countries and networks, modify the TCP-specific parameters, stored within the parameter category NCC.X.ADI_MFC. You can modify parameters that program TCP/host interaction, that configure unregulated features or features that can change from switch to switch within the same network. You can freely edit these parameters to suit your implementation.

The following table describes the NCC.X.ADI_MFC parameters that you can modify:

Field | Type/ Unit | Default | Description
--- | --- | --- | ---
DIDnumber | count | 7 | Inbound: Number of DID digits to expect.
ANInumber | count | 8 | Inbound: Number of ANI digits to expect.
DIDBeforeANI | count | 1 | Inbound: Number of DID digits to receive before asking for category.
nobusyonReject | mask | 0x0 | Determines if the TCP plays busy when rejecting a call. If not, the switch does it instead. 1 - Do not play. 0 - Play (default).
trunkdirection | mask | 0x0 | Determines trunk direction: 0 - Bidirectional. 1 - Inbound only (no calls can be placed on it). 2 - Outbound only (no calls can be received on it).
cleardowntone | mask | 0x0 | Determines if a cleardown tone (busy tone) is necessary when the inbound side of the TCP hangs up a call first: 0 - No cleardown tone is played. 1 - Play cleardown tone.
norejtoneUserAudio | mask | 0x0 | Plays a message while rejecting a call. If set to 1, the TCP sends the backward Group B tone to the network to accept the call, thus causing the network to establish the voice path. The TCP then waits for the far end to hang up while the application plays a message.
detectnetworkAudio | mask | 0x0 | If this parameter is set to 1, the TCP starts call progress in any case after an outbound call is accepted by the network, so that a message or SIT tone can be detected. Call progress detection by default is not started if the user sets the connectmask to connect on SIGNAL. This value saves DSP resources.
answerGroupA | mask | 0x0 | If this parameter is set to 1, the TCP answers an incoming call from Group A without asking the network for the caller's category (Group II forward tone). The caller's category will therefore be missing from the incoming call-related information delivered to the host.
