Frame Type Framing format. The following two framing formats differ in the

number of frames per superframe and in the use of the F-bit

position. A frame comprises 24 timeslots of 8-bit data preceded by

a bit called the F-bit.

• D4 – Twelve frames make up a superframe. The F-bit provides

frame and multiframe alignment information.

• ESF – Twenty-four frames make up a superframe (extended

superframe). The F-bit provides Facility Data Link (FDL) and

CRC information as well as frame and multiframe alignment

information.

Line Bldout T1 transmit power level measured in length of cable connecting the

router and associated T1 equipment; ranges from 1 to 655 feet.

B8ZS Support Status of Bipolar Eight Zero Substitution — On or Off. B8ZS

maintains sufﬁcient “ones” density requirements within the T1 data

stream without disturbing data integrity.

Clock Mode Source of the T1 transmit clock, as follows:

• Internal – Clock is generated internally.

• Slave – Clock is derived from the incoming data stream.

• Manual – Jumpers on the T1 Link Module determine the clock

source (Internal or Slave).

MiniDacs Conﬁguration Function assigned to each of 24 DS0 channels (timeslots). The

table shows these functions in a string of 24 characters, one

character per channel. The characters and their meaning are as

follows:

• 1 – Assigns the timeslot to the ﬁrst HDLC controller (Circuit 1).

• 2 – Assigns the timeslot to the second HDLC controller (Circuit

2).

• D – Assigns the timeslot to data passthrough (HDLC controller to

HDLC controller).

• I – Assigns the timeslot to idle.

• V – Assigns the timeslot to voice passthrough (HDLC controller

to HDLC controller).

For example, the sample display shows the Mini Dacs

Conﬁguration on circuit 21 as:

1111111111111111IIIIIIII.

This string shows timeslots 1 - 16 assigned to the HDLC controller

(1) and timeslots 17 - 24 idle (I).
