1.1 Overview

The NPRAE (New Primary Rate Access E1) board replaces the PRA2 board.

This board can be used to connect an Alcatel-Lucent OmniPCX Enterprise CommunicationServer to:

- Another Alcatel-Lucent OmniPCX Enterprise CS in a private network (ABC-F, Q-SIG)

- A non Alcatel PBX in a private network (DPNSS)

- A public network (ISDN, DASS2)

The NPRAE board can provide either:

- Two E1–CCS (T2) accesses

- One DASS2 access (as of R6.1)

- One DPNSS access (as of R6.1)

Note:

For DASS2 and DPNSS, access 0 is the only access available.

At initialization, binaries are sent according to the type of board declared on the PCX. Thesetypes are:

- NPRAE for E1-CCS

- DASS2E for DASS2

- DPNSSE for DPNSS

Clock synchronization can be obtained from the board access if needed to synchronize thenode.

NPRAE board configuration is described in NPRAE - Hardware configuration .

NPRAE board connection is described in NPRAE - External connections .

2.4 Meaning of LEDs

Figure 2.6: NPRAE Board Front Panel

Under CPU/BSY line, the first column of LEDs gives information on the DASS2, DPNSS or firstE1 link, the second column gives information on the second E1 link.

table 2.1: Summary TableLED Meaning Explanation

CPU (green LED) Processor activity indicator

BSY (orange LED) Trunk activity indicator (for atleast one trunk)

LOS Loss of frame alignment After detecting incorrect framealignment.

AIS Alarm Indication Signal (2 Mbitsalarm signal)

Incoming signal is an unframed bitstream with constant ’one’.

RAI Remote Alarm Indication Distant line end signalizes an alarm.

NOS Loss of Signal Input signal has an insufficient bit rateor an insufficient density of ones.

Note:

No led is available for CRC error ratio.

3.1 Connection

The NPRAE board is inserted in an interface position in the ACT shelf.

Figure 3.1: Connecting the NPRAE Board

If the connection is:

- by cable: connection to the main distribution frame is via a type 2 cable (see TY296PTSDIN cable - Hardware description),

3-1

Note:the second T2 interface is distributed on the pairs corresponding to the first T0 interface of a BPRAboard.

- by coaxial cable: connection to the data transmission equipment is via 4 type 5 cables (seemodule TY5 9PTS DIN/BNC cable - Hardware description),

Caution:the NPRAE board uses the same 75 ohm cables as the PRA2 board, but the first link receptioncable (75 ohms) must be connected to position 18–20, instead of position 10–12 for the PRA2board.

- by patch panel (VH cabinet only): connection is directly performed using the patch panel:16-port 4-wire module (see Patch Panel - 16 ports module - 16 ports module).
