Maintenance DLCI

The TA 850 can be configured from theWAN without having to preset a DLCI mapping or IP address.

This value is the DLCI number used to open an IP session by theTA 850. Any IP packet arriving from

the PVC is assumed to be for the TA 850’s IP stack. The destination address in the packet is assigned as

the PVC’s local IP address. The source address is used to add a host route in the routing table. The

default is 901, but any legal DLCI number can be used.

BECN Timeout

This value is expressed in milliseconds and represents the amount of time the TA 850 will stop transmit-

ting over a PVC which received a packet with the BECN bit set. The default is 1.5 seconds.
