Brief Introduction
¡¡¡¡BZDXC256 is a small-content cross connection equipment
with max. 8 standard E1 interfaces, supporting 75¦¸/120¦¸
impedance. It has 4¡Á4, 2¡Á2, 3¡Á1 and other connection types
to realize the flexible cross connection of 248 time slots in
the 8 E1 lines to guarantee the data inter-frame integrity. At
the same time, it can also transfer the CAS signal message
a/b/c in Ts16.
The product is widely used in China Telecom,
China Mobile, China Unicom, and communication networks for
public security, electric power, railway, etc.
