Chapter 1 Introduction Optimux-XLT1 Installation and Operation Manual
1-6 Functional Description
A selection of Ethernet, Fast Ethernet, T1 and high-speed channel modules permits
a variety of multiplexing schemes for LAN and CO sites. The Ethernet or Fast
Ethernet ports are connected directly to the local network or to an Ethernet LAN.
The port activity and the link integrity are monitored either by front panel LEDs or
by an external terminal. The transmission of the Ethernet or Fast Ethernet channel
is implemented by a built-in bridging function operating at the 6.639 Mbps,
"almost wire-speed", rate and supports up to 10,000 (Ethernet) or 16,0000 (Fast
Ethernet) addresses.
The T1 interface complies with the ITU-T Rec. G.703. Line coding is B8ZS. A pair
of LEDs monitor loss-of-signal and AIS on each T1 receive line.
For the high-speed modules (V.35, RS-530 and X.21), the desired physical port
connector is achieved by the use of an appropriate adapter cable, which is
supplied with the product.
Management Requirements
Optimux-XLT1 operates locally using on-board switches and jumpers to configure
the operation modes and front panel LEDs to monitor system failure and tests
(loop connections). Alarms are monitored using the dry contacts of the
Optimux-XLT1 alarm relays on a dedicated D-type connector.
An ITU-T V.24/EIA RS-232 port enables monitoring and tests using an ASCII
supervision terminal.
The management interface also includes an SNMP agent that enables SNMP
management of the Optimux-XLT1, using the Ethernet protocol. The SNMP
management capability enables fully graphical, user-friendly management using
the RADview network management stations offered by RAD, as well as
management by other SNMP-based management systems.
Remote management is also possible using the Telnet communication protocol,
which uses TCP/IP communication, without the SNMP service. Telnet support
enables a remote IP host to control the operation of Optimux-XLT1 using functions
identical to those provided by a supervision terminal. The Telnet management
function can be protected by the manager password feature.
When using Telnet for management, the Software Downloading option is not
operational.
