offers the STM-1,
VCL100CPE (with 14 E1)
and with one tributary interface card (E3 / DS3 / Ethernet) is an
ultra-compact and cost-effective customer premises bandwidth
provisioning STM-1 SDH multiplexer equipment designed to meet low or
medium capacity bandwidth service demands.
Following tributary choices are available:
The chassis is 19" rack or wall
mountable as per customer requirements
STM-1 interfaces depending on Terminal multiplexer or Add-Drop
This is provided through the 10/100 Mbps NMS (Ethernet)
port or an RS232C craft port.
External 2Mbps or 2.048 MHz timing signal inputs are
provided for synchronizing the equipment. Further, reference 2Mbps
reference output is provided.
This is provided through the analog 2-wire interface. The
EOW bytes are software selectable to E1 or E2.
Potential free contacts
These provide dry contacts for extending the alarms. Five such
potential free outputs are provided that are tied to alarms for
Critical, Major, Minor, Order Wire and Power. Two potential free
inputs are provided for environmental alarms like "Power or
Air-conditioning failure", "equipment room door open" etc.
E1 Tributary Card
E1 / DS1 tributary card are supported in a single chassis.
10/100 Mbps Ethernet Tributary Card
Ethernet Tributary Card maps 10/100 Mbps Ethernet data on
to VC-12's with a rate adaptation granularity of 2 Mbps. Each port's
bandwidth is configurable in increments of 2Mbps, based on per port
user demand. The aggregate bandwidth from each ETC card is at most
STM-1 line rate (63 VC-12 worth of traffic).
Power Supply Unit
Power to all the cards in the chassis is distributed from
this unit accessible from the rear. This is running off a -36V to
-60V DC supply.
