Product News

PN 06:16 Rev A 2006-10-20

Created by ESF/KEP/MA Francois Vaillant

Alternatively, a greater capacity 12 V / 12 Ah or 24 Ah battery of a sealed lead-acid

type (type YUASA NPL 12-12 or YUASA NPL 24-12 respectively), not supplied, may

be installed externally to the system cabinet to ensure longer system autonomy in

case of a mains failure.

For the MD Evolution Mi/ EBN (rack version) any 12V battery may be installed

externally to the system cabinet.

CCS4-S Settings

The only setting allows selection of the ringing frequency for the analogue stations: 20,

25 or 50Hz. A switch, on the left side of the CCS4-S board is accessible when the

system cabinet is open.

CCS4-S cabling

The CCS4-S board is connected to the CPJ5/CPJ6 board through a power supply flat

cable, provided.

The CCS4-S board is connected to the 230 Volts - 50 Hz mains source using a 3-wire

230 Volts + Ground power supply cord, which is 3 meters long. Three types of power

cord are available (please check the Ordering Information whether the correct power

cord is included in the ordered system package):

o one compliant to EU standards (always provided with the

CCS4-S),

o one compliant to GB standards,

o and one compliant with USA and Canada standards.

The CCS4-S board can be also connected to the optional back-up battery:

o For connection of the 12 V - 7 Ah internal battery (MD

Evolution M/ EBN wall mounted version), the two battery

power wires are provided and directly connected to CCS4-

S board.

o For connection of an external battery, the above power

wires may be replaced by longer (maximum: 2 meters) 2.5

cross section power wires, not provided.

5.3 New ISDN PRA protocols T1 for North American

markets

This enhancement applies only to MD Evolution M/Mi systems.

Previously the MD Evolution was only supporting the ISDN PRA signaling

compliant with the European standard ETS 300 403-1. In Europe, it is the E1

interface that has 32 time slots (2 Mbits/s). Voice codec is in A-law.
