All of these might not be available on an FRX4000. It depends on which protocols were
purchased. Also, note the guidelines in the explanation. X.25 is always loaded, and is not
a configurable option. This prevents the possiblility of deleting X.25, which is a nec-
essary protocol for use by internal SmartSwitch traffic.

Protocol
determines which protocols can run in the node. Although the FRX4000 contains a
group of protocols in the software when shipped to the customer, they must be loaded
into the operating software (by configuring them in the RLP file, then rebooting the
node).
Follow these guidelines when configuring protocols:
●
RIP is a valid choice only if IP is already specified.
●
If SNMP is configured, IP must also be configured.
●
If LLC2 is configured, BRIDGE must also be configured.
●
If NVSP is configured, LLC2 and BRIDGE must also be configured.
With the exception of X.25, protocols must be configured in the Protocol
file before they can be configured on ports.
T1 LIC Parameters
Line Coding
specifies the physical line encoding technique used to carry clock signals, per AT&T
ACCUNET T1.5 Service Description and Interface Specification. Note that B8ZS
stands for Bipolar Eight Zero Code Substitution, and AMI is Alternate Mark
Inversion.
Framing
specifies the T-1 framing format, per ANSI T1.403, 1995. Note that ESF stands for
Extended Superframe Format.
Line Service
determines whether full or channelized T-1 will be run over the LIC port.
