The table of TDM switches can store up to 64 entries, indexed starting from 0 up to 63.
The entry priority index sets the switch verification order and must be sequential.
The priority index for TDM switches is also utilized as a reference for operations of insertion, modification and deletion.
In the table of TDM switches, configurations may be added, modified, deleted while the Abilis CPX is working, without needing to restart it. Changes made in the table are immediately actives by executing the command INIT TDM.
Commands for handling the table of TDM switches are described in the TDM switches section of the chapter Commands relating to the Enhanced ISDN Router. The available commands are the following:
A TDMHere it follows an example of the TDM switch visualization. All values are only examples.

| PR: | TDM switch priority: the highest priority is 0 |
| no value | from 0 up to 63 |
This is the TDM switch entry priority. The priority value sets the verification order of the TDM switches table entries: starting from the highest (0) and proceeding to the end of the table (at maximum up to 63).
The priority index is also used by the adding, modifying, deleting commands to refer to a given TDM switch.
TDM switches table is automatically updated every time it is modified, so that priority sequential order is kept and no "free places" are left into the table.
| SERVICE: | Type of service associated to the TDM switch |
| Unused | Unused, VSP, sQ931, Q931 |
It sets the type of service associated to the TDM switch.
| Value | Meaning |
|---|---|
| Unused | It stands for "no service". It is the default value associated by the command A TDM. |
| VSP | It stands for Virtual Synchronous Port service. |
| sQ931 | It stands for simulated Q931 service. |
| Q931 | It stands for Q931 service. |
| MODE: | Type of channel(s) used by the service.(Only for SERVICE:sQ931/Q931) |
| BIDIR | BIDIR, INCOMING, OUTGOING |
It sets the type of channel(s) used by the service sQ931 or by the service Q931, which the TDM switch refers to:
| Value | Meaning |
|---|---|
| BIDIR | Bidirectional channels |
| INCOMING | Incoming channels |
| OUTGOING | Outgoing channels |
This parameter can be changed only when the SERVICE: parameter is set to "Q931" or "sQ931" value.
| VSP-ID: | Identifiers associated to the VSP service (Only for SERVICE:VSP) |
| NONE | NONE, 1 - 32 |
It sets the identifier associated to the Virtual Synchronous Port (VSP) service, which the TDM switch refers to.
This parameter can be changed only when the SERVICE: parameter is set to "VSP" value.
| PO: | ISDN/EBISDN/EPISDN port which the TDM switch refers to TDM |
| NONE | NONE, 0 - 999 |
It specifies the port which the TDM switch refers to. The specified value must correspond to a configured port of ISDN, EBISDN or EPISDN type.
| CH: | Channels used by the service which the TDM switch refers to. |
| NONE | NONE, 1 - 31 (more than one values can be joined by using ',' (comma), and/or '-' (minus)) |
It specifies the channel or a group of channels used by the service, which the TDM switch refers to.
Intervals of values are allowed by using the ',' (comma) character and/or the '-' (minus) character.
For example the value: "CH:1-3,5-8,20-22", indicates that channels from 1 to 3, 5 to 8, 20 to 22 are in use.
For VSP services type only contiguous intervals are allowed.
For example it is allowed to set "CH:5-20", while it is not allowed the following "CH:5-10,12-20".
If the port specified in the parameter PO: is a Basic Rate port, then the interval allowed will be [1 - 2].
