-
Assign a DLC/DTX board using OM command ASBRDS and the correct sub-signalling
groups (ASPCTB) to operate the SOPHO-LAM in DTE mode (see Appendix C);
-
Set the board and circuits in service condition INS using OM command SETINS;
-
Assign DNRs to the line circuits of the DLC/DTX to which the convertors are connected
using OM command CHDNRC;
-
Assign IBSC `64 kbit/s unrestricted' (IBSC=0) to the DNRs of the SOPHO-LAM
convertors using OM command CHDNRS;
-
Assign the correct Terminal Endpoint Identifier to the SOPHO-LAMs used (TEI=0 or
TEI=1; first or second B-channel respectively). For programming the TEI value refer to
the Customer Engineer Manual of the SOPHO-LAM P375.
-
Define a group of convertors (a convertor pool) using OM command CRGRPA. GROUP-
PROPS:
- empty group allowed
- group hunting
- hunting sequence
- automatic COB
- call pickup
- pickup to group only
- observation group
- ACD
GROUP-DISPLAY=0;
SUPERVISOR-DNR and PARK-POS are not used;
-
Download the CV information towards the SOPHO-LAMs using OM command
DOWNLD;
-
If required, project a Permanent Line Extension using OM command CHPLEX;
-
If required, project a hotline relation using OM command CHHOTL;
-
If required, program the predefined destination DNR in the convertor SOPHO-LAM;
-
Ensure that the convertor modem is configured for leased line operation;
-
Ensure that the convertor modem operates in the silent mode (result codes disabled) You
can set this option using Hayes command ATQ1;
-
Ensure that CT108 of the convertor modem is continously on (108.2 mode; Data
Terminal Ready);
-
Ensure that CT107 indicates the condition of the analogue line (normal operation
according to V.24 specifications).
This means the following:
-
CT107 is OFF in the idle state;
-
CT107 goes OFF when the Hang Up process is started;
-
CT107 goes ON as soon as the connection set-up is started;
-
CT107 goes ON in the V.25(bis) dialog mode.
