T25 (Data Packet Retransmission Timer) -

Specifies the amount of

time, in seconds, that the DTE waits for the appropriate acknowledgment
after transmitting a data packet. If the T25 timer expires, the packet layer
resets the virtual circuit.

T26 (Interrupt Timer) -

Specifies the amount of time, in seconds, that the

DTE waits when an Interrupt Request packet is sent for an interrupt
confirmation to be received. If the T26 timer expires, the packet layer
resets the virtual circuit.

R20 (Restart Retransmission Timer) -

Specifies the maximum number

of times the local DTE retransmits, upon expiration of the T20 timer,
before notifying the user that the associated link is inoperative.

R22 (Restart Retransmission Counter) -

Determines the maximum

number of times the local DTE retransmits a Reset Request packet, upon
expiration of the T22 timer, before initiating a Clear procedure for SVC
or a Restart procedure for PVC.

R23 (Clear Retransmission Count) -

Determines the maximum number

of times the local DTE retransmits a Clear Request packet upon
expiration of the T23 timer, before initiating a Restart procedure on the
associated link.

Logical Channel Numbers

PVC, Lowest LCN -

Determines the lowest LCN used for a PVC.

PVC, Number of LCNs -

Determines the number of logical channels

supporting PVCs. This number must agree with your network
subscription.

Inbound SVC, Lowest LCN -

Determines the lowest LCN that can be

used for one-way incoming logical channels for SVCs. This value must
be greater than or equal to the lowest PVC LCN parameter value.

Inbound SVC, Number of LCNs -

Determines the number of incoming

channels assigned for inbound-only SVCs.

This number must agree with your network subscription.

Two Way SVC, Lowest LCN -

Determines the lowest number of two-

way channels assigned for SVCs that can be used for both inbound and
