- System Parameter 175 — PORT NUMBER FOR CALL RECORDS TO FIRST PORT.
These settings are site specific and depend on the numbering of PBX extensions. The following is an
example of settings for the four parts of this parameter:
- Number of digits in the extension number fields to 5
- Number of digits in the port number field to 3
- Fill character to 0 (zero)
- Port number used in call records to 1
- System Parameter 198 — PCM ENCODING FOR THE SYSTEM.
Set to
1 , for A-law.
Voice data is encoded, in the E1 environment, into 8 bit numbers (called octets) that are sent 8000
times per second for each port. This process of sampling and encoding analog voice to these octets is
called Pulse Code Modulation (PCM). PCM uses two standard algorithms for conversion: A-law,
which is used primarily in Europe, and U-law, which is used in North America. If DTIC voice quality
sounds consistently bad but still recognizable, the DTIC could be operating with the wrong PCM law.
To correct this low voice quality, change the PCM law and restart the message server.
⇒
Important: If a DTIC card is configured for A-law, 4- or 8-port line cards cannot be used:
- To receive fax calls
- For modem connection using the # # # 5 command
Class of Service
A COS must be configured for each of the 30 DTIC ports. Assign attributes as required. Refer to the
Configuration volume, COS chapter.
LSP Table
LSP tables are preconfigured and exist in the system. The LSP Table defines control parameters for
different DSP-based line/trunk interface cards and the DSP-based integration cards. Each LSP Table has
fields that define values for control parameters needed for correct operation of the card. These values are
downloaded to the card when it boots up.
In UPDATE, the LSP Tables can be listed by the command LIST LSP . If problems exist because of an
LSP Table configuration, information about these parameters is useful if it is necessary to call technical
support for help.
SLOTS Table
The slot in which a DTIC is to be installed must be added to the SLOTS Table. Adding a slot for a DTIC
is similar to adding a slot for other line cards. However, there are some questions pertaining specifically
to the DTIC.
Slots can be skipped, as for any line cards. However, the grounding strip is for only the first seven slots.
With Capacity on Demand, the number of ports for the DTIC are purchased as required.
After the slot is configured, the system must be restarted for the DTIC to become operational.
