LIU Modifiers

This subsection describes each modifier contained in the PCP6LIU profile and all other

modifiers that can be used with the LIU protocol. For detailed information on using the

Subsystem Control Facility (SCF) to alter the default values for the duration of the

current session, refer to Section 8, Managing CP6100 Using the Subsystem

Control Facility (SCF). For detailed information on permanently altering the modifier

default values contained in the PCP6LIU profile or creating a new profile, refer to the

WAN Subsystem Configuration and Management Manual.

ANY

This modifier is an operational class modifier that allows you to select the operational

class of the LIU download module. If an appropriate module is not found in the

download file, the operation terminates. ANY is the default operational class for the

PCP6LIU profile.

The ANY modifier allows the line to be configured as byte-synchronous,

bit-synchronous, or asynchronous. ANY also specifies that the CONMGR does not

check the type of line configured. Specifying the ANY modifier means that once your

system is in an operational state, you can specify the specific type of line you are using

through SCF.

ASYNC

This modifier is an operational class modifier that specifies the operational class of the

LIU download module as asynchronous. If an appropriate module is not found in the

download file, the operation terminates. ASYNC is the default operational class for the

PCP6MPSB profile.

When the ASYNC modifier is included in the PROFILE file, the ConMgr process

checks to make sure that the operational modifier specified in the microcode file

matches the line configuration. If they do not match, the microcode download does not

occur; however, you will not receive an SCF error. If the operational modifier does not

match the line configuration, you will receive a system error stating that the microcode

was not downloaded after the attempted download to the CLIP.
