It is intended for
E1/T1 transmission between digital automatic telephone exchange,
from channels making multiplexer MK-30, IKM-6A/30 by our manufacture
and the equipment of other manufacturers. The modern method of
coding of a line signal – TC-PAM16 is applied in the equipment.
The equipment MK-30TC10 provides E1/T1 transmission on one pair
with regeneration section on 10 km in cable with S=1,2 mm2 and
6 km - in cable with S=0,5 mm2
Equipment model MK-30TC10 can be
applied for replacement of equipment model IÊÌ 15õ2 "Zone" at
"digital" area as lengths of regeneration sections at them are
identical. On sections where cable with S=1,2 mm2 is working now
IKM-15 and IKM-30 with line code HDB3, MK-30TC provides an opportunity
of E1/T1 transmission with reduction of quantity of regenerators
and with simultaneous liberation of one pair. At 5 regenerator
sites the total length of action of system is 75 km.
So on cable with
S=1,2 mm2 two Å1/T1 can be transmitted, and with the help of MK-30TP
transcoder - four, that is 120 channels of voice-frequency E&M
(connecting lines or direct subscribers of regional automatic
telephone exchange
Cost of MK-30TC10 - 3 200 $ USD

MK30-TC10

| Networking of E1/T1 transmission at one pair in cables
with S = 1,2 mm2 with length of regeneration section up to
10 km. It is used for E1/T1 transmission between two ATE or
other equipment under protocol G.703. |
