Switch S2-4: Line Framing and Coding

Use Switch S2-4 to control the Network Line Framing and Coding Options. Set these options to be the same as the Line Framing and Coding Options given to you by your Service Provider. If you are using two Model 2720s together as short range modems, set both units iden- tically.

S2-4 Line Framing & Coding

Off ESF/B8ZS

On D4/AMI

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.

Switch S2-5: DS0 Channel Rate

Use Switch S2-5 to set the DS0 rate.
