The VCL100MC-1 STM-1 (upto 63
E1) with E3, DS3, 10/100BaseT Ethernet interfaces is a compact, modular and
cost effective STM-1 SDH multiplexer equipment designed to manage bandwidth
and provide E1 or fractional E1, voice and data access service over STM
Networks.
VCL100MC-1 (upto 63 E1) with E3,
DS3, 10/100BaseT Ethernet interfaces is a 3U height multi-card chassis
system that provides flexibility to the customers in terms of expansion to
support additional client interfaces by adding new modules in the field.
The system has two STM-1 optical / electrical interfaces in the aggregate
side and allows for upto 3 tributary add-on cards. The following tributaries
are available as add-on cards for the chassis:
- E1
- E3/DS3 tributaries
(software configurable as E3 or DS3)
- 10/100Base-T Ethernet
(IEEE 802.3)
- STM-1o
- STM-1e/140Mbps tributary
interfaces (software configurable)
Hardware
components
Chassis
The base chassis houses the following:
STM-1
interfaces
STM-1 optical / electrical interfaces are supported depending on Terminal
multiplexer or Add-Drop Multiplexer configuration.
Management interfaces
This is provided through the 10/100 Mbps NMS (Ethernet) port or an
RS232C craft port.
Timing Interfaces
External 2Mbps or 2.048 MHz timing signal inputs are provided for
synchronizing the equipment.
Order-wire
This is provided through the analog 2-wire interface. The EOW bytes
are software selectable to E1 or E2.
Alarms
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.
A 2.048 M BITS clock output is available from
the system, which can be set to either a 2.048 MHz clock or a framed E1 data
at 2.048 Mbps
