TANDBERG MPS ADMINISTRATOR GUIDE

LED’s for the E1/T1 PRI Interface Card (IIC-8)

You will find 4 Light Emitting Diodes (LEDs) for each PRI interface which provides information about PRI-line status.

Read the LEDs for each of the PRI interfaces on the E1/T1 Interface Card from left to right:

1.Red LED - If On this indicates Layer 1 Red Alarm

2.Yellow LED - If On this indicates Layer 1 Yellow Alarm

3.Green LED - If On this indicates Layer 1 OK

4.Red LED - If On this indicates that D-channel is Down

Red Alarm or Loss of Signal (LOS) indicates that there is no signal and thus no framing info received. The same effect will be obtained by pulling out the PRI cable. This may also be caused by a broken connector in the receive (RX) part of the cable.

Yellow Alarm or Remote Alarm Indicator (RAI) means that the MCU is receiving framing info, but in this framing info the other side tells the MCU that it is not reading the MCU’s transmitted framing info. Typically, this may be a broken connector in the transmit (TX) part of the PRI cable. This could also indicate weak or noisy signal in the transmit (TX) part of the PRI cable.

Green LED or Layer 1 OK doubles as a clock source indicator. The LED for one of the eight interfaces will flash to indicate that the interface is being used as the clock source for H.110 bus.

•On - Layer 1 OK, not clock source

•On + Flash (long On/short Off) Layer 1 OK, used as clock source

•Off - Layer 1 Down, not clock source

•Off + Flash (long Off/short On) Layer 1 down, used as clock source

Channel Service Unit

Channel Service Unit (CSU)

The PRI interface may require an external CSU (Channel Service Unit) depending on the network layout.

The Cable Length in the PRI configuration menu specifies the distance from the MCU to the CSU or last repeater.

PRI Protocols

The TANDBERG MPS supports the PRI protocols

•AT&T Custom

•National ISDN

•Japan/Taiwan ISDN

•ETSI (Euro ISDN)

•The AT&T, Japan ISDN and National protocols gives a total of 23 B-channels per port

•The ETSI protocol gives a total of 30 B-channels per port.

Within these protocols the following switches are sup- ported:

Channel Hunting

Channel Hunting

Channel hunting is provided for outgoing calls. The feature is normally used when the number of channels needs to be specified.

•When no value is specified for low or high channel, they are default to 1 (low), 23 (high US) and 30 (high Europe).

•Default search is from high to low.

Red Alarm or D-Channel Down indicates that the ISDN out-of-band signalling channel is down. The D channel carries user-network signalling information and is primarily used in call setup and teardown. Note that for NFAS the D channel may not be used for all PRI interfaces. A red LED may thus not indicate anything wrong.
