4.2.2 STS-1 Multiplexer Module (P/N 1181030L2)
The Total Access 3000/3010 STS-1 SONET Multiplexer provides a full STS-1
SONET multiplexer in a single slot of a Total Access 3000/3010 chassis. This single
1-inch wide card provides a SONET terminal multiplexer in an extremely small space
and includes time slot assignment for all VT1.5s delivered through the STS-1 network
interface. Redundancy is supported but not required, so the system can have either one
or two STS-1 multiplexers installed. If two are installed, they share the same network
interface, with one of the units active and the other in hot-standby mode. See Figure 8.
Up to 28/22 VT1.5s can be delivered through the STS-1 multiplexer. However,
installing the multiplexer does not eliminate the office repeater capability of the
system, so a single system can have an STS-1 and several DSX-1 network interfaces
simultaneously. Full DS1 time slot assignment capability allows any DS1 delivered
from a VT1.5 in the STS-1 signal to be delivered to any slot in the system. The DS1
can be delivered out of the system in many different forms, including repeatered T1,
HDSL and DSX-1 for local delivery of the DS1.
