VCL-STM-1
(upto 63 E1)
Hardware System
Orion Telecom Networks Inc. offers 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
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.
