Product Brief

Ke y Fe a tu re s

Ge n e ra l De scrip tio n

The digital interface on the ‘exchange’

side uses the industry-standard GCI

interface in 2 Mbit burst mode. This

mode allows for 8 channels to be multi-

plexed onto the same interface. The

MTC-20278/ 9 can be set to respond to

either the first 4 or the last 4 timeslots in

the GCI frame. This allows two devices,

totalling 8 ISDN lines, to be multiplexed

onto the same GCI interface.

The MTC-20278/ 9 chip contains all

the functions necessary to make 4 ‘U’

interfaces in an ISDN Line Termination

card. It comprises 4, fully integrated

echo-canceling ‘U’ interfaces, confor-

mant to the ‘Uk0’ interface point, plus

the necessary support and test func-

tions. The general block diagram is

shown in Figure 1. Two versions of the

device are available - the MTC-20278

offering the 2B1Q line code, and the

MTC-20279 which has 4B3T line cod-

ing. Both devices are pin compatible,

and are fully compliant with the rele-

vant parts of ETSI, FTZ and ITU

The MTC-20278/ 9 takes all timing

information from the GCI clocks, and

so does not require a separate clock

oscillator.

The MTC-20278/ 9 devices offer a

user transport rate of 144kbit/ s full

duplex (2B + D) per channel, as well

as fully automatic control of

activate/ deactivate protocols and line

supply, and full support of the mainte-

nance channel.

The MTC-20278 offers facilities

required for the synchronisation of

DECT base stations (“heart beat” and

loop length estimation)
