Cable And Distances; Connecting The Ergoline Terminal - Philips ErgoLine D330 Manual

Cable and Distances

The S interface consists of two balanced twisted pairs, one pair for Transmit and
0
one pair for Receive. The distance between the ErgoLine and the Switch depends
upon the configuration and the cable characteristics of the cable used between
the wall socket and the Main Distribution Frame (MDF).
The U interface consists of one balanced twisted pair with half duplex operation
PN
being used. The cable length is defined by cable type.

For the possible wiring configurations, see the chapter "Cables and Distances" on
page 2-4 of the ErgoLine D330/D340 section of this manual. Note however that
the ErgoLine D310 and D320 cannot be connected to a DLC-C or DLC-D via a
PNT1.
Both twisted pairs must be terminated (preferable in the wall socket) with a 100 Ω
resistor.
Note 1: When using a cable with cable characteristics different from the
ones listed in Table 5.1, the lengths of cable required will be different.
Note 2: An intermediate MDF in the connection can also affect the overall
cable characteristics.
Note 3: When cables are connected together additional attenuation,
caused by the joints, will occur.
When an ErgoLine D310 or D320 terminal is connected via a PNT1 to a DLC-U, the
distance can be extended by 1500 m. In this case the attenuation of the cable
used between the PNT1 and DLC may not exceed 15dB (at 100kHz, without noise
insertion).
Any combination of two ErgoLine models (D310, D320, D330 or D340) can be co-
located. This means that different models (e.g. a D320 and a D340) may be
connected to the same S0 bus. They are identified by TEI or EAZ.

Connecting the ErgoLine Terminal

Connect the D310/D320 as follows:
• connect the handset into the handset port, and put the handset on the
cradle
• plug in the telephone line cord at the wall socket or the PNT1
