The IMUX 2160 in slot 4 uses 4 T1 circuits with a V.35 rear
interface module (DIM 2635). The IMUX 2160 in slot 9 uses 8
T1 circuits with a HSSI rear interface module (DIM 2660).
NOTE: Since the V.35, RS-449 and EIA 530 electrical interfaces only
provide reliable operation at rates up to 6 Mbit/s, any
QUAD/IMUX installation which uses more than 4 T1 circuits
or more than 3 E1 circuits requires the use of a HSSI rear
connector module (DIM 2660) for the IMUX 2160. HSSI is
designed to provide reliable operation at up to 52 Mbit/s.
•
The DTE (Data Terminal Equipment) to be connected at each
site consists of TCP/IP routers. At the central site two different
WAN ports of the same router will be connected to the two
QUAD/IMUX installations.
•
All of the T1 circuits use ESF framing and B8ZS line coding.
