1.1 - General
The ADR 155C is an optical STM-1 add-drop multiplexer used to build STM-1 point-to-point
links, STM-1 rings, or mesh networks with conduct (SNC) or line (MSP) protection, so
performing the conveyance of links at 2 Mbit/s, Ethernet, STM-1.
The ADR 155C can be used as:
S
STM-1 terminal multiplexer with maximum capacity of 63 VC12 and capability of 1+1
protection,
S
STM-1 repeater, capability of regenerating 2 VC4,
S
STM1 multiplexer with insertion/extraction, with maximum capacity of 4 STM-1 and
insertion/extraction of 21 VC12
S
LAN interconnection point (in exclusive function up to 3 remote links totalling 3 VC3 used).
This equipment is managed from a HTTP navigator:
S
either locally, via its dedicated Ethernet interface
S
or remotely by teleoperation
S
or from the IONOS-ANM network manager; in this last case, using the SNMP protocol also
allows global network supervision.
Using a local terminal with VT100 emulation is necessary on the first commissioning, for the
configuration of communication parameters.
Management network connections are performed via DCC D1 to D3 (or D4 to D12) of the STM1
or on Ethernet (ETH) or P (MNGT) interfaces of the equipment.
The ADR155C is placed in 19" racks or ETSI frames. It consists of:
S
a 2U subrack fitted with a motherboard grouping together the basic functions of the
equipment, a backplane and a secured 48V DC power supply,
S
an ADRFAN module, consisting of two redundant ventilation units,
S
four traffic cards:
S
IC1.1 or IC1.2 STM1 optical card (ADR IC1.1 or ADR IC1.2 card) allowing a VC4
connection or 3 VC3 connections or 63 VC12 connections or a combination of VC3/VC12
connections
S
21 x 2 Mbit/s card, G.703, (ADR21E120 card), allowing 21 VC12 connections
S
Ethernet 10/100 card (LAN1 ADR card), allowing 2 VC3 connections.
