# EAM editable parameters

To program the pulsed E and M TCP to operate within different countries and networks, modify the TCP-specific parameters, stored within the parameter category NCC.X.ADI_EAM. You can modify parameters that program TCP/host interaction, that configure unregulated features, or that configure features that can change from switch to switch within the same network.

The following table describes NCC.X.ADI_EAM editable parameters (within the parameter category NCC.X.ADI_EAM):

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 | 0x1 | 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 | Use this parameter if you need to play a message while rejecting a call. If set to 1, the TCP sends to the backward Group B tone 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.
askrepeat | mask | 0x0 | If set to 1, the TCP asks the network to send the complete ANI digit string for an inbound call. If 0, the network may send partial ANI.
timewaitdial | ms | 500 | Outbound: Inactive time between the end of an outbound call and the next outbound call. Needed to synchronize the parties in those cases when a release guard signal is not in the protocol.
