DESCRIPTION
• IPmux-16 provides a compact,
simple to configure, easily scalable
solution for transporting TDM
E1/T1 and E3/T3 services over IP
and Ethernet-based networks.
• IPmux-16 is suitable to be located
at a central site or POP,
aggregating TDMoIP traffic from
multiple sources.
IPmux-16
TDMoIP Gateway
• IPmux-16 takes data streams from
up to sixteen E1/T1 or up to two
E3/T3 ports and converts them
into packets for transmission over
the network (see Table 1). The
addressing scheme of these
packets is IP. The frames are
transmitted via the Ethernet
modules to the network. A second
TDMoIP gateway at the remote
location converts the IP packets
back to TDM traffic.
• The primary benefit of IPmux-16
is to allow transparent E1/T1 and
E3/T3 connectivity over Layer 2/3
packet networks, both in carrier
and enterprise environments
• IPmux-16 is a standard IP device,
supporting ICMP (ping), ARP,
next hop and default gateway
capabilities.
• IPmux-16 complies with the
TDMoIP protocol, working in
conjunction with IPmux-1,
IPmux-1E, IPmux-8,
Megaplex-ML-IP,
Kilomux KML.11, and other
third-party products that
implement the TDMoIP protocol.
APPLICATIONS
• IPmux-16 features a dry contact
alarm port that can serve as a
general-purpose input port. The
alarms are classified into three
categories, stored in the event log,
and can generate a system trap
that is sent to the NMS.
PERFORMANCE
• Type of Service (ToS) of the
outgoing IP frames is
user-configurable. This allows an
en-route Layer-3 router or switch,
which supports ToS (or Diffserv),
to give higher priority to IPmux-16
traffic for delay-sensitive
applications.
• IPmux-16 can achieve end-to-end
processing delay as low as
1.7 msec, using high-performance
buffering and forwarding
techniques.
• IP packet size is configurable.
Greater packet length results in
greater processing delay, yet a
smaller bandwidth overhead.
• An enhanced buffering
mechanism compensates for
packet delay variation (jitter) of up
to 32 msec for E1, 24 msec for T1,
and 20 msec for E3/T3.
QOS SUPPORT
• IPmux-16 supports VLAN tagging
and priority labeling according to
802.1 p&Q.
• User traffic VLAN-based
separation is supported by
applying a dedicated VLAN tag to
every TDMoIP circuit, and a
dedicated VLAN for managing the
device.
Figure 1. Extending E1/T1 or E3/T3-based Services over IP
• Assigned, IANA-registered UDP
socket number for TDMoIP
simplifies flow classification
through switches and routers.
OPERATION MODES
• Two types of service are offered:
Unframed: Full E1/T1 or E3/T3
circuits are transparently
extended across the IP network,
regardless of framing structure.
Structured: IPmux-16 can be
configured on a per timeslot
basis for fractional E1/T1 services
over IP networks. CAS signaling
is supported.
• Multibundling (grouping timeslots
originating from a specific E1 or
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-16 allows internal
cross-connect of bundles between
its E1 or T1 ports.
TIMING
• IPmux-16 maintains
synchronization between TDM
devices by deploying advanced
clock distribution mechanisms.
The clocking options are:
Internal: The IPmux-16 clock’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.
External: The station clock port
is available and may be used to
synchronize E1/T1 interfaces.
ETHERNET MODULE
• Two Ethernet modules can be
installed in the IPmux-16 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 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-16 is equipped with two
Ethernet modules (see Figure 5).
E1 AND T1 MODULES
• Each E1 or T1 module provides
either four or eight standard E1 or
T1 interfaces, which enable
connectivity to any standard E1 or
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 are all supported.
Standard E1/T1 alarms are
supported end-to-end.
E3 AND T3 MODULES
• Each E3 or T3 module provides a
single, standard E3 or T3 interface.
• 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
are all supported. Standard E3 or
T3 alarms are supported
end-to-end.
POWER SUPPLY
• The IPmux-16 modular power
supply supports carrier
environments. The maximum
power supplied by one unit is
75W with maximum power
consumption of 57W.
• IPmux-16 features hot-swappable
power supplies, enabling service
to a power supply (see Figure 4
and Figure 5).
DIAGNOSTICS & MANAGEMENT
• IPmux-16 supports remote loop
and local loop testing.
End-to-end alarm generation and
end-to-end AIS indication are also
provided. In the event that a local
E1/T1 port receives AIS, it is
passed to the remote port via the
Ethernet/IP network. If a local
Ethernet port is not connected, an
AIS indication will be generated
both in the local and the remote
devices.
• On the E1/T1 or E3/T3 ports, SES
and UAS statistics are collected in
15-minute intervals and are stored
for 24 hours (96 intervals). E1/T1
physical layer alarms (LOS, AIS,
LOF, LCV) are also supported.

IPmux-16
TDMoIP Gateway
• IPmux-16 features a dry contact
alarm port (with a DB-9
connector), which allows the
device to send/receive alarms by
opening/closing the contact
between the connector's pins.
• IPmux-16 monitors LAN and IP
layer network condition statistics,
such as packet loss and packet
delay variation (jitter). The events
are stored in log files and SNMP
traps are generated.
• IPmux-16 performs an internal
built-in test (BIT) after power-up.
The results of the test are visible
via the local terminal.
• Software download is supported
via the local terminal using
XMODEM, or remotely, using
TFTP. After downloading a new
version of software, IPmux-16
automatically saves the previous
version in non-volatile memory for
backup purposes. Similarly, copies
of the configuration file may be
downloaded/uploaded to a
remote workstation for backup
and restore purposes.
• IPmux-16 can be configured and
monitored:
Locally, via an ASCII terminal or
over the local management port
Remotely via Telnet or SNMP
(RADview Service Center
TDMoIP)
The RADview Service Center
package enables provisioning
TDMoIP service and managing
the TDMoIP gateways by
providing a user-friendly
graphical display that allows
monitoring and configuring of
multiple IPmux devices. Fault
isolation, statistics and events
gathering are available. The
Service Center’s intuitive GUI
interface, "point-and-click"
functionality and easy-to-follow
wizards increase the efficiency
and accuracy of the service
provisioning process.
