OPERATION MODES
• Two types of service are offered:
Unframed: Full E1/T1 circuits
are transparently extended
across the IP network, regardless
of framing structure.
Structured: A bundle of timeslots
can be configured for fractional
E1/T1 services over IP networks.
CAS can be enabled.
• Multibundling (grouping timeslots
originating from a specific E1/T1
port) can be performed for up to
31 bundles per E1 port and
24 bundles per T1 port, for
transport over the network. Both
mesh and star topologies are
supported.
• IPmux-8 allows internal
cross-connect of bundles between
its E1/T1 ports.
TIMING
• IPmux-8 maintains
synchronization between TDM
devices by deploying advanced
clock distribution mechanisms.
The clocking options are:
Internal: The device’s internal
oscillator provides the master
clock source for the TDM
circuit.
Loopback: The transmit clock is
derived from the respective
port’s receive clock.
Adaptive: The clock is recovered
from the Ethernet network
interface.
ETHERNET MODULE
• Two Ethernet modules can be
installed in the IPmux-8 chassis,
providing the uplink to the packet
network.
• Each module supports a single
10/100BaseT or 100BaseFx port.
• IPmux-M/ETH/UTP,
IPmux-M/ETH/MM-LC, and
IPmux-M/ETH/SM-LC modules
support re-ordering when packets
arrive from the network in the
wrong order, without considering
them as lost packets.
• Ethernet link redundancy to the
network is supported when
IPmux-8 is equipped with two
Ethernet modules.
E1 AND T1 MODULES
• Each E1/T1 module provides four
standard E1/T1 interfaces, which
enable connectivity to any
standard E1/T1 device
(see Ordering).
• Integral LTU/CSU can be enabled
for line protection and long haul
applications.
• Alarm detection and insertion are
supported together with error
statistics, SES/UAS statistics,
LOS/AIS physical layer alarms and
remote loop/local loop test
modes. Standard E1/T1 alarms are
supported end-to-end.
POWER SUPPLY
• Power supply is available for AC
or DC.
• IPmux-8 features optional
redundant power supplies.
