To program the digital ground start TCP to operate within different countries and networks, modify the TCP-specific parameters stored within the parameter category NCC.X.ADI_GDS. 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 GDS parameters (within the parameter category NCC.X.ADI_GDS) that you can modify:
Field |
Type/ |
Default |
Description |
---|---|---|---|
nodialtonebehavior |
mask |
0x0 |
Determines what to do if no dialtone is detected: 0 - The TCP hangs up and abandons the call. 1 - The 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 |
0x0 |
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. |
hangupsignal |
mask |
0x0 |
Flags that control the bit that signals hang up supervision. Cleardown tone is always detected. Bit 0 (&0x1): Hang up supervision on the A bit (default). Bit 1 (&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) |
