Chapter 5 Terminal Operation
5-3
In the above screen, Time Slot number applies to originating time slot of all ports. The "d" means the time
slot is assigned for data channel, "v" means for voice channel, "s" means for signaling channel. If time slot
carries voice, A-law to µ-law conversion is automatic. Under PORT A, "NONCAS" means CAS (carrier
associated signaling) is not used. Under PORT D, "v F 02" means that time slot 02 of PORT D, which
carries voice, is assigned to time slot 02 of PORT F.
The above example is the first page of System Setup (MAP) screen, which displays 01 to 16 time slots. Use
SPACE key to view the second page of System Setup (MAP) screen, which shows 17 to 31 time slots.
As for PORT D, "FE1 CAS" means that CAS is chosen for an E1 port, because time slot 16 is already
assigned to signaling channel, a warning message will show up and the assignment will be ignored if user
tries to use time slot 16 to carry data or voice. Thus time slots 01 to 15 (PAGE1) and 17 to 24 (PAGE2) are
available assigned to data or voice channel.
Under PORT E, "FT1 NONCAS" means that CAS is not chosen for T1 port, thus time slots 01 to 16 (PAGE1)
and 17 to 24 (PAGE2) are available assigned to data or voice channel.
Under PORT J, "DTE V.35" means the port type is DTE (V.35), thus time slots 01 to 16 (PAGE1) and 17 to
31 (PAGE2) are available for assignment.
NOTE:
When a time slot from a CAS part is assigned to a NON-CAS port, all CAS signaling information is
lost. Therefore, such assignments are usually made for time slots carrying data.
To change any of the MAP settings, use the arrow keys to move the cursor to the desired field and then
modify that field. Modification of fields is either (a) by using the TAB key to cycle through the options, or (b)
for time-slot assignment, by using backspace to erase and by using the numeric keys to enter a new number.
For example, when the cursor is at the target port field, pressing the TAB key will cycle the target port or
blank, which indicates idle assignment. When the target port is blank, the time-slot is 00. When the cursor is
at the target time-slot field, user can enter a new last digit, or use the BACKSPACE key first to enter both
digits.
When the user enters a new time-slot assignment, and if the target port and time slot is idle, then the
reciprocal assignment is automatically made when the user moves the cursor away from that field. However,
if the target port is not idle but already a part of a pair of time slots previously assigned, then that pair of
assignments will flash to warn the user of possible conflicts. If the user chose to ignore the flashing warning
and move the cursor away from the field with the desired assignment, then the new target port and time-slot
will be changed to reflect the new reciprocal assignment. The third time slot, the other half of the previously
assigned pair will be changed to idle.
