Introduction
Chapter 482
ST26INTPT (110) The VC has received an Interrupt Packet. The data
buffer contains up to 32 bytes worth of interrupt data.
ST26ICONF (111) Interrupt Confirmation packet received for this
Virtual Circuit. The remote DTE has confirmed the
Interrupt packet which was sent.
ST26LCENB (112) VC ZLU has been enabled. This indicates that the
VC ZLU is now in the enabled state. At this point, the
ZLU is available to place a call (SVC) or for
transferring data (PVC).
ST26LCTPA (113) VC ZLU has been activated. If the virtual circuit was
in a flow control state (RNR sent), then an RR has been
sent and inbound data will now be accepted by this
virtual circuit.
ST26LCUP (114) The Virtual Circuit is now in the UP state. That is, it
is available for data transfer operations. For SVCs this
status message indicates that the call setup processing
is complete. You should not attempt to send data until
this status message is received. This status message
also contains 16 bits of data containing the Logical
Channel Number (LCN) used for this Virtual Circuit.
ST26LCDN (115) The Virtual Circuit is now in the DOWN state. This
status message usually indicates the completion of the
Call Clear processing for an SVC. Note that if you have
issued a Clear Request, you should not attempt to place
a call on this VC until you receive this status message.
This status message also contains two bytes of data:
Byte 1 = Cause code
Byte 2 = Diagnostic code
ST26LCTPD (116) The VC ZLU has been deactivated. This status
indicates that the VC has been placed into an inbound
flow control mode. That is, an inbound data packet on
this VC will result in a level 3 RNR being transmitted.
ST26LCDSB (117) The VC ZLU has been disabled. A disabled VC ZLU
may not be used to accept or place calls (SVC) or to
transfer data (PVC). Any call that was established has
been cleared.
