Functional Description of Table TERMDEV

Table TERMDEV lists the assignments for terminal devices.

The operating company completes the input for table TERMDEV.  The switching unit Input/Output Controller (IOC) assignments to the terminal devices are shown on Northern Telecom drawing number D610.

See table MTD (Magnetic Tape Device) for the terminal devices that have fixed assignments on the IOC.

Assign the Trunk Test Positions (TTP) devices in order: TTP:00, TTP:01, TTP:02 and so on, until all the TTP devices are assigned.  Only then can the rest of the printers and Visual Display Units (VDU) be entered in the table.

WARNING!  Lockout Condition Can Occur.  A lockout condition exists if all commands are set as privileged-classed (PRIVCLASS) out for all users and terminals.  The only way out is to use the user identification (userid) ADMIN.  An ADMIN userid is neither displayed nor restricted in any way.  It is always available, provided the ADMIN password is known and the terminal is not in the automatic login (AUTOLOGIN) mode.

If the DMS switch is under a heavy load, a number of terminals and one log device must continue to run despite the call processing or maintenance load.  The base support is accomplished by having guaranteed background tasks.  Guaranteed tasks are limited in number, so they run more frequently than other tasks.

The following devices can be guaranteed.

In table TERMDEV no more than five devices can be guaranteed, and in table LOGDEV only one device can be guaranteed.  These devices are assigned by the customer through datafill in tables TERMDEV and LOGDEV.  Any user logging into any of these devices has a guaranteed response.

Field GUAR is set to N (no) by default, and must be changed if this feature is to be used.

Note:  Access to table TERMDEV can be restricted by datafilling table CUSTPROT.  For operating companies in the United Kingdom, access to this table must be restricted by datafilling table CUSTPROT, to prevent the customer of third party system maintenance from reconfiguring terminal data and affecting automatic dial-back or terminal command class restrictions.

If the switching unit contains feature AD0179 (ACD Real Time Display Enhancement), the datalink device must be datafilled in table TERMDEV and table SLLNKDEV in order to be connected in LNKUTIL and used to generate the ACDRTD (ACD Real Time Display) reports.

If the switching unit contains feature package NTX243AA (AMA Teleprocessing System), table TERMDEV must be datafilled for each of the two recording devices in the Device Processing Peripheral (DPP) unit.  TERMDEV must be datafilled for the DPP links before datafilling table DPP.  For reliability, care must be taken to datafill terminals that are associated with different IOCs.

When datafilling table TERMDEV, table CUSTPROT, table SUBPROT, or table CMDS, do not use the same class number twice; the system does not distinguish between class numbers for commands and class numbers for system data table access privilege.  As the PERMIT command is used to assign privilege classes for commands and for access to tables, accidental duplication of a class number can cause the PERMIT command to provide not only the intended access to a command, but also unintentional access to a table.

If a change to table TERMDEV affects the terminal data used by table DPP, the affected tuple must be deleted from table DPP before deleting the tuple from table TERMDEV.

Effective BCS30, with the 1X67FA device controller card for the Simplified Message Desk Interface (SMDI) feature, two C-side links enable outgoing messages sent from Central Control (CC) to the card to be received over C-side link 0 (zero).  Outgoing messages sent from the card to the CC are routed over C-side link 1.

With two C-side links, datafilling table TERMDEV with a console device using a 1X67FA terminal controller card requires two tuples.  When the first tuple is added manually, a second tuple is added automatically by table control.

There is a two-tuple restriction placed on field TERMDES when datafilling a console device using the 1X67FA terminal controller.  In this instance, there is a maximum field length of seven characters.  When the second tuple is added automatically, the second, unique tuple name takes the name of the first tuple, followed by the capital letter I.

When datafilling table TERMDEV with a console device that does not use the 1X67FA card, the maximum length of a tuple name in field TERMDES is eight characters.

For related information, refer to table MTD.

Datafill Sequence :  Table IOC must be datafilled before table TERMDEV

Table Size

Memory is automatically allocated for the maximum number of 128 terminal devices, which includes 59 SMDI-type console devices and 64 non-SMDI devices; the remaining five entries are reserved for other uses.
