In both cases, the transmitter uses the smoothed clock.

2.6 OPERATING MODE SELECTIONS

There are two data modes in which the interface passes data and timing:

• Octet Mode—This mode preserves the byte integrity associated with

Octet timing. The Octet timing frame is embedded in the data.

Note

Octet timing mode is supported only when two 1082/F modems

are connected to each other. It is not supported when the

1082/F modem is used with the 1092A or 1092ARC modems

from Patton.

• Clear Channel Mode—Data is passed at a 64K rate. This does not

preserve the byte integrity associated with Octet timing. Instead, an

Octet timing alarm (on or off) is passed over the modem similar to the

way signaling leads are passed.
