| It represents the interface type assigned to a channel.
The following different types of interfaces are possbile:
Number InterfaceType A B C D CondName
1 {User Config, U, U, N, N, a},
2 {Unconfig, U, U, N, N, a},
3 {No Sig, U, U, U, U, a},
4 {Force Sig, U, U, N, N, a},
5 {2W E&M, 0, X, N, N, a},
6 {4W E&M, 0, X, N, N, a},
7 {FXO, 1, 1, N, N, b},
8 {FXS G/S, 0, 1, N, N, c},
9 {FXS L/S, 0, X, N, N, d},
10 {DPO, 0, X, N, N, a},
11 {DPT, 0, X, N, N, a},
12 {RPO, 0, X, N, N, a},
13 {RPT, 0, X, N, N, a},
14 {SDPO, 0, X, N, N, a},
15 {DX, 0, X, N, N, a},
16 {ETO, U, U, N, N, e},
17 {PLAR, U, U, N, N, d},
18 {PLR, 0, X, N, N, a},
19 {RD, U, U, N, N, a},
20 {R1 (SOCOTEL), 0, N, N, N, e},
21 {SSDC5A, 1, 1, 0, 1, f},
22 {R2 (backward), 1, 1, N, N, e},
23 {R2 (forward), 1, 0, N, N, d}
Where
A B C D are the signalling bits corresponding to Onhook values
having the following meanings:
0 meaning 0
1 meaning 1
X meaning donot Care
U meaning unknown
N meaning not used
and the Conditioning templates can be any of a b c d e f types.
If the IPX receives A B C D bits corresponding to the on-hook
values, that channel is known to be on-hook. Otherwise that
channel is known to be offhook. Each interface except for
UserConfigured type has a pre-determined conditioning template
associated with it which are of 5 different types apart from
user configurable conditioning templates.
Examples of valid values are any of the above interface number
given above.
If it is a userConfigured OR Forced Signalling (FCDSIG = 4) interface
type then the following variables need to be supplied:
voiceChannelIfOnhkABit
voiceChannelIfOnhkBBit
voiceChannelIfOnhkCBit
voiceChannelIfOnhkDBit
voiceChannelIfCondName.
If any of the above variables are not provided with values then, the
current values in the data base is retained.In all other cases the
values are as shown in the table above.
The interface type is ignored for 'D' type connections.
The default values for a channel:
InterfaceType A B C D CondName
UnConfigured U U N N a.
If a pre-defined Interface type is chosen in a SET, values for the
other related objects should not be provided. |
