IPmux-155L
Hub-Site Pseudowire Access Gatewa
MANAGEMENT CAPABILITIES
The unit can be managed using different
ports and applications:
Local out-of-band management via a
terminal connected to the RS-232 port
Remote out-of-band management via
the dedicated 10/100BaseT port
Remote inband management via the
GbE or FE interface. Remote
management is performed using Telnet
or RADview, RAD’s SNMP-based EMS.
Software is downloaded via the local
terminal, using XMODEM/YMODEM, or
remotely, using TFTP/FTP.
The Syslog protocol is used by IPmux-155L
to generate and transport event
notification messages over IP networks to
the central Syslog server. The Syslog
operation is compliant with the RFC 3164
requirements.
OAM AND STATISTICS
Comprehensive monitoring and diagnostic
capabilities include port status indication
and statistic counters for Gigabit Ethernet
and STM-1 interfaces.
RAD’s TDM PW OAM mechanism verifies
connectivity and prevents pseudowire
configuration mismatch.
ALARM REPORTING
The device includes a dry-contact
connector for reporting alarms to external
equipment. The connector also has an
external alarm input for monitoring
external sensors.
TIMING
IPmux-155L features a flexible clock
mechanism using external and internal
timing signals coming from:
SDH clock (8 kHz)
2.048 MHz clock recovered from a PW
flow, E1 line or GbE port (Sync-E)
External station clock source via
station clock port, providing
out-of-band synchronization.
DIAGNOSTICS
For diagnostic purposes, IPmux-155L
maintains a cyclic event log file that stores
up to 2048 time-stamped events and a
real-time current alarm list.
To verify the TDM link integrity,
IPmux-155L provides local or remote
loopbacks on the VC-4 and E1 interfaces.
User-activated BER tests can be generated
to analyze E1 streams.
An internal built-in test (BIT) performed
after power-up checks the internal
circuitry of the unit. The results of the test
are visible via the local terminal.
