Layer 1 State
The operational state of the physical connection (Layer 1) of the ISDN link
carried over the port:
activated = Layer 1 frames are being passed between the port and BRI
endpoints.
pend-activation = The port is in service, the layer 1 interface device
is turned on and layer 1 frames are being sent from the port, but the BRI
endpoints are not responding.
deactivated = The layer 1 interface device on the BRI has been turned
off due to the port being out of service.
TEI Value
The Terminal Endpoint Identifier (TEI) is a layer 2 addressing parameter
used by the switch to exchange information with BRI endpoints over the
point-to-point signaling link. The TEI is a number from 1 to 127.
Layer2 State
The operational state of the point-to-point signaling link (Layer 2):
assigned = The link is currently in the AWAIT_EST (Await Establish)
state at layer 2. If the BRI endpoint supports TEI allocation procedures,
those procedures have been successfully executed and a TEI has been
assigned to the endpoint by the switch.
established = The link is in the MF_EST_NORM (Multi-Frame
Established Normal) state at layer 2. The switch has successfully started
the link and is now capable of exchanging layer 3 frames with the endpoint.
If the endpoint does not support SPID initialization procedures, the voice
extension of the endpoint associated with the link is also displayed. This is
the normal state for a link in a point-to-point wiring configuration.
L3-established = The link is in the MF_EST_NORM state at layer 2
and SPID initialization procedures have been successfully completed. The
voice extension of the endpoint associated with the link is also displayed.
This is the normal state for a link in a multipoint wiring configuration.
hyperactive = Traffic on this link has exceeded the threshold and the
link has been suspended.
Endpt
Extension
The extension of the voice/data endpoint associated with the link. This field
is blank if the link is not in the
established or L3-established
state.
Endpt SPID
The SPID (Service Profile Identifier) administered for the voice/data
endpoint. This field is blank if the link is not in the
established or
L3-established state.
Service SPID?
If the link is associated with the Service SPID this field displays yes and
the Endpoint Extension field is blank. Otherwise this field is blank. Service
SPID is a feature used by service technicians to check building wiring
between the switch and the BRI endpoint.
