Recommendations
D
Sync support: The number of sync channels supported over the frame
relay access link depends on the link's rate and the CIR (Committed
Information Rate) implementation of the frame relay switching
equipment and network congestion characteristics.
- It is recommended that you use the SNAPS option for SNA traffic
to reduce delay and network traffic.
- It is recommended that sync speeds be 19.2 Kbps or higher. If you
are using a slower speed, the block size should be short.
- TDM sync channels are not supported.
D
Voice/Fax support: The number of voice/fax channels supported over
the frame relay access link depends on the link's rate and the CIR
implementation of the frame relay switching equipment and network
congestion characteristics. (Generally this is 80% of the CIR.)
- Voice channels configured for continuous bandwidth are not
supported.
