Main link modules
The single or dual E1/T1 and ML-IP main link
modules incorporate the DS0 matrix between
the I/O channels and each of the E1/T1 trunks.
The modules support 8 Mbps non-blocking cross
connect for any DS0 coming from either the
channels or from the trunks. Multiple fractional
E1/T1 ports are supported. These main links
support 1+1 protective switching for any E1/T1
port.
The eight E1/T1/DSL main links support a higher
capacity of 16 Mbps when used together with
the HS-12 module, but do not support
redundancy.
Four timing options are available:
•
Link receive clock
•
Internal crystal oscillator channel
•
Clock from any high speed module (HS-6N,
HS-12N, HS-S, HS-U, HS-703, HS-Q/N)
•
Station clock
Any clock source can be set as the fallback in
the event of primary clock source failure.
Ring support (E1/T1 and RFER)
The Megaplex supports various ring topologies
ensuring “no single point of failure.” E1/T1 ring
protection provides self-healing in less than five
seconds. Resilient Fast Ethernet Ring provides a
100 Mbps (up to 40 E1/50 T1) Ethernet ring
with self-healing in less than 50 msec.
Alarms
Alarm information is stored in the common logic
module and is automatically read by the
management system from any node. Up to 256
alarms can be stored in a queue, and a maximum
of 1,024 alarms can be stored in a file on the PC,
to be read by the management system.
System modules
The common logic module stores configuration
and event information, and uses a SLIP/PPP or
Ethernet connection to communicate with the
management station via an SNMP agent. Flash
EPROM for remote software download, Telnet and
an ASCII craft terminal are also supported.
