Configuring the C100/C150 Using the Console Port
06/17/97 C100 and C150 T1/FT1 CSU/DSU 6-7
Idle or busy fill character
This field selects the fill character, either an Idle or a Busy for insertion
into the DSX-1 output in all DS0s used by the Synchronous Channel.
With Idle displayed, an Idle character is inserted into all the unused
DS0s on the DSX-1 interface. With Busy selected, a Busy character is
inserted into all the unused DS0s. Typically the Idle character is the
insertion character. On a few older PBXs, the Busy character is
required.
Pressing the SPACE bar when on the Fill Character field advances the
blinking cursor to the Sync Channel Interface selection.
C100/C150 Synchronous channel interface
This field is used to select the interface on the Synchronous Channel.
With 422/530 selected, the interface selected is RS422/RS530 and all
the interface signals are on the DB 25 pin female connector on the rea
of the unit. With V.35 selected, the interface selected is CCITT V.35 and
all the interface signals are on the 34 pin female Winchester connector
on the rear of the unit. With RS232 selected, the interface selected is
RS232 and all interface signals are on the DB 25 pin female connector
on the rear of the unit. Both the 34 pin and 25 pin interface cables must
not be connected at the same time.
56000 or 64000
This field determines whether the bandwidth of all DS0s to the
Synchronous Channel is 56000 or 64000 bps. With 56000 selected, all
DS0s to the Synchronous Channel are 56000 bps. To calculate the
Channel speed, multiply 56000 times the number of DS0s going to the
Channel. If 4 DS0s were selected to go to the Synchronous Channel, the
Channel speed would be 224000 bps. Selecting 64000 in this field, gives
64000 bps to all the selected DS0s going to the Channel. The same
calculation applies when using 64000 bps. Multiply 64000 times the
selected DS0s to calculate Channel speed. The following referenced
chart lists all the multiples of 56000 and 64000 bps available with the T-
1 CSU/DSU.
Carrier (Receive Line Signal Detect) Control
