# OPS editable parameters

To program the off-premises station TCP to operate within different countries and network, modify the TCP-specific parameters, stored within the parameter category NCC.X.ADI_OPS. You can modify the TCP/host interaction that configures unregulated features or modifies features that vary from switch to switch within the same network.

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

Field | Type/ Units | Default | Description
--- | --- | --- | ---
nodialtonebehavior | mask | 0x0 | Determines what to do if no dialtone is detected: 0 - TCP hangs up and abandons the call 1 - TCP proceeds to dial anyway
transfersupport | mask | 0x0 | Selects whether PBX transfer is allowed: 0 - Transfer commands are disabled 1 - Transfer commands are allowed
CIDsupport | mask | 0x0 | Indicates if caller ID is supported: 0 - CID disabled 1 - CID enabled
cleardowntone | mask | 0x1 | If network side, tone to play as dial tone (if 0, do not play cleardown tone): 1 - Play dial tone as cleardown tone 2 - Play busy tone as cleardown tone 3 - Play reorder (fast busy) as cleardown tone
cleardownflag | integer | 1 | Turns on cleardown detection: 0 - Off 1 - On
hangupsignal | mask | 0x1 | Flags that control the bit that signals hang up supervision. The cleardown tone is always detected. 0x1 - Hang up supervision on the A bit (default) 0x2 - Hang up supervision on the B bit
trunktype | mask | 0x0 | Determines the trunk type: 0 - T1 1 - E1
signalingtype | mask | 0x0 | Determines the signaling type: 0 - Foreign exchange (FX) 1 - Special access (SA)
