All of these might not be available on an FRX4000. It depends on which protocols were

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.

ACCUNET T1.5 Service Description and Interface Specification. Note that B8ZS
stands for Bipolar Eight Zero Code Substitution, and AMI is Alternate Mark
Inversion.
specifies the T-1 framing format, per ANSI T1.403, 1995. Note that ESF stands for
