Multilink Point-To-Point Protocol; Ppp And Stac Compression - ADTRAN Express 3010 Manual

as other ISUs using a single configuration. This allows for integrating
services without changing the configuration on the Express.
The Express must be optioned as follows for FALLBACK operation:
• Any asynchronous bit rate up to 115.2 kbps which is supported
by the DTE.
• Flow control must be enabled and supported by the DTE.
FALLBACK supports the following protocols based on the call type:
BONDING mode 1, V.120, and PPP async-sync. When answering
calls, the Express uses the incoming call type to determine which rate
adaption protocols to support.
When originating calls to unknown units, the ISU begins protocol se-
lection based on the local call type. Data 64k is used for FALLBACK
selected from the Profiles menu. Upon connection at 64k call type,
BONDING, V.120, and PPP async-sync are attempted. If connection
is not made at 64k, the Express attempts another call at 56k call type.
If connection is made at 56k, V.120, and PPP async-sync are attempted.

Multilink Point-to-Point Protocol

This protocol allows the Express to dial a second number, establishing
a second point-to-point link. Once the second PPP is established, mul-
tilink PPP is performed over both B-channels. The phone number for
the second call should be placed in stored number 1 (SN1). If no num-
ber is stored in SN1, the same phone number dialed to establish the
first link is used for the second link.

PPP and STAC Compression

When set up to do compression, the Express will negotiate the com-
pression control protocol (CCP) with the network PPP peer. If STAC
compression is successfully negotiated with the peer, data packets
from the DTE are compressed before being sent out the network. Like-
wise, compressed packets from the network are decompressed before
being transmitted out the DTE.
