Line Framing Options:

D4/Superframe: The D4 framing format, as specified in AT&T TR62411 is the standard in which twelve frames make up a superframe. All signaling and synchronization are done in- band.

Extended Superframe (ESF): Extended Superframe, as speci- fied in AT&T TR 54016, consists of twenty-four (24) T1 frames. The framing bits are now used for framing, CRC and the Facility Data Link (FDL). The FDL allows maintenance messages and information to be passed between the 2720 and the Central Office.

Line Coding Options:

Alternate Mark Inversion (AMI): This mode does not inherently account for ones density. To meet this requirement, each time slot can be reduced to 56 kbps and the Least Significant Bit (LSB) of each time slot set to one.

Bipolar 8 Zero Substitution (B8ZS): This mode assures proper bit density in the data stream. In this mode any data pattern can be transmitted without causing ones density errors. This mode allows for 64 kbps clear channel timeslots.

NOTE 1: When using the Model 2720 as a high-speed short range modem, one unit of the link must be configured in Internal Clock mode, and the opposite end unit must be configured for Network Clock mode.

If the ERR LED on the front of the unit is flashing (or on) it could be an indication of a clocking problem. Double check your clock mode settings and Tx Clock Invert S1-3 settings.
