Full range of traditional functionalities of STM-1 level SDH systems Ethernet 100 and V.11 interfaces for
LAN-traffic and data Open management system based on SNMP agent
Fiber-optic Synchronous Digital Hierarchy (SDH) transmission systems AccessGain A155/T155 can be
successfully applied for installation of first hierarchy level STM-1 core networks. Add/drop nodes are based
on AccessGain A155 multiplexer, also for two “rings” conjunction. AccessGain T155 is used for installation of
terminal nodes and “point-to-point” connections.
AccessGain systems A155/T155 are also used as high-speed transmission subsystem of universal platform
AccessGain. SDH multiplexer AccessGain A155/T155 being combined with AccessGain access system
allows complete access network installation with the single platform. Such network is optimized for TDM
(leased lines), IP (Internet access) and POTS (connection to PSTN) services. All management functions are
provided by single system AccessGain View (SNMP based).
In AccessGain A155/T155 systems only the robust components of very-high integration level are used. Due
to this the competitive cost, high reliability and low power consumption have been achieved. Compact size
(19” case 2U height) allows AccessGain A155/T155 to be installed into existing operator’s 19’ rack.
AccessGain A155/T155 contains removable interface modules, which allows flexible SDH nodes
configuration while network is being developing
