>> Table: isdnIfTable - (.1.3.6.1.4.1.272.4.2.1.1)
Description: The isdnIfTable contains information relating to the interfaces found on the system. Each entry corresponds to a connected ISDN interface (BRI or PRI). Entries can only be added or deleted by the system. Creating entries: Entries are created by the system only when a new BRI or PRI module is installed. Deleting entries: Entries are removed by the system after the appropriate BRI or PRI module is removed.

Index
Unique index of the basic or primary rate interface.
Description
Textual description of the basic rate interface including its slot and number (e.g. bri2-0 means slot 2, unit 0). Length: 0 to 255
Layer1State
The ISDN physical layer state according to I.430 f1(1) = inactive; f2(2) = sensing; f3(3) = deactivated; f4(4) = awaiting signal; f5(5) = identifying input; f6(6) = synchronized; f7(7) = activated; f8(8) = lost framing; g1(9) = deactive; g2(10) = pending activation; g3(11) = active; g4(12) = pending deactivation Enumerations: f1 (1) f2 (2) f3 (3) f4 (4) f5 (5) f6 (6) f7 (7) f8 (8) g1 (9) g2 (10) g3 (11) g4 (12)
BchannelControl
B-channels are controlled by a call control protocol in the D-channel. Otherwise they may be used as permanent links. Enumerations: uncontrolled (1) controlled (2)
ActivationRequest
When this object is set to 'activate' the BRICK will start an activation sequence of ISDN-Layer1 of the basic rate interface. Enumerations: nooperation (1) activate (2)
Mode
Specifies the mode of the interface. TE or NT Mode will be set for ISDN interfaces without PABX control. For PRI both NT (network termination) and TE (terminal equipment) modes are supported. If hardware is detected to be in a different state than contained in configuration (and it isn't programmable concerning mode but only changable by means of jumpers), isdnIfOperState becomes failed. Enumerations: te (1) nt (2) pabx-terminal (3) pabx-trunk (4) pabx-tie (5)
TimerT3
Value of Timer T3 in milliseconds.T3 is started whenever ISDNLayer-1 is activated (i.e. Activation Request is started).
UsePowerDetector
Use the PS1 Power Detector to control the layer 1 automaton.This object is only valid for basic rate interfaces. Enumerations: use (1) dontuse (2)
NumberOfChannels
Number of Channels including the D channel, that are available on this ISDN Interface (3 = BRI, 31 = PRI). Range: 1 to 31
Timeouts
Number of timeouts of T3 during lifetime of the system.
Activates
Number of successful activation cycles during lifetime of the system.
Deactivates
Number of deactivations during lifetime of the system.
AutoconfigState
Start auto configuration on this ISDN Interface. Auto configuration is a mechanism to automatically detect the attributes of an ISDN interface. This can be done at boot time (if isdnIfAutoConfig is set to 'on') or by manually setting this field to 'start'. Refer to Chapter 3 on Features and Methods. Enumerations: start (1) running (2) done (3)
Autoconfig
Start Autoconfiguration on this ISDN interface at bootup. Enumerations: on (1) off (2)
LicenseUsage
Shows which license type is currently used for this ISDN interface. Enumerations: none (1) missing (2) pri (3) g703 (4) bri (5)
BriIfType
For some basic rate ISDN hardware it is possible to switch line interface type between S and U interface by using dedicated header modules. As this hardware property may also influence configuration on higher protocol layers, it is reflected here as well as made permanent when a configuration gets saved. For primary rate interfaces (PRI) this variable has no meaning. Enumerations: s (1) u (2)
AdminState
This variable allows for taking an ISDN interface out of/in service w/o having to touch the configuration. Besides, it is possible to initiate a reconfiguration for that interface in case a mismatch in configuration parameters (hardware vs. software) was detected. Inconsistencies with the need of reconfiguration are differing - isdnIfMode (te/nt), and/or - isdnIfBriIfType (s/u) In case of mismatch, contents of mentioned variabled might be wrong and this circumstance is reflected in variable isdnIfOperState. State reconfig may then be used in order to cause an update of these variable as appropriate which ... - will be signalled to higher protocol layers, and - can result in extensive reconfiguration steps The latter may also cover clean-ups undoable by system so this decision is left to the user. Default value is down. Enumerations: down (1) up (2) reconfig (3)
OperState
The operational state of an interface is indicated via this variable. Possible values are: - down(1), - running(2), - fail(3), - stopped(4), - stopping(5), - starting(6) The latter two states being of transitional type, mainly for hot-plug type hardware, and won't be normally seen by user. State fail is used to reflect inconsistencies between hardware state and configuration concerning interface mode (isdnIfMode) and, for basic rate interfaces, type (isdnIfBriType). Enumerations: down (1) running (2) fail (3) stopped (4) stopping (5) starting (6)
Slips
Slip conditions detected since startup. Flags that the frequency of receive clock is different than frequency of internal system clock.
