PNT1 (for use with 4-wire interface)
The ErgoLine D330 and D340 can be connected to the Switch via a Private
Network Termination (PNT1). This is an interface converter for OSI layer 1 and 2
between the echo-cancelling U interface (proprietary Philips) used on digital
subscriber lines in the SOPHO ISPBXs and the ISDN basic rate S
0
interface. At OSI
layer 3 the PNT1 is transparent.
A maximum two ErgoLine D330 terminals or two ErgoLine D340 terminals can be
connected to the PNT1.
The default TEI of the ErgoLine D330/D340 is 0. If two sets are connected to a PNT1
in a voice mode only situation, one of the sets requires the TEI to be changed to
1.
If the ErgoLine D340 is to be used in a speech and data mode, only one set can
be connected to the PNT1. The TEI in this configuration must be set to 0 and 1.
The PNT1 is equipped with two eight way modular sockets for the connection of
two S
0
ErgoLine terminals. On both jacks the corresponding pins 3, 4, 5 and 6 are
interconnected: 3 to 3, 4 to 4, etc.
When the ErgoLine terminal is line powered, power provision is done via pin 3 & 6
(positive polarity) and pin 4 & 5 (negative polarity) when the power source is in
the normal power mode.

Interface
This interface is the standard SOPHO iS3000 S

interface.
U
PN
interface
The ErgoLine D330 and D340 can be connected to the switch via the DLX-U U
PN
interface. This is a two wire digital interface which uses ping-pong signalling. (Do
not mistake this interface with the echo-cancelling proprietary Philips U-interface).
This interface is only capable of supporting the connection of one terminal.
When the card is projected in 1B mode, the terminal requires a TEI setting of 0.
When the card is projected in 2B mode, the terminal requires the following setting:
•
Terminal with speech service only requires the TEI setting of 0 (default)
