DESCRIPTION
• IPmux-16 provides a compact,
simple to configure, easily scalable
solution for transporting TDM
E1/T1, E3/T3 or channelized T3
(CT3) services over IP and
Ethernet-based networks.
• IPmux-16 can be located at a
central site or POP, aggregating
TDMoIP traffic from multiple
sources.
IPmux-16
®
TDMoIP Gateway
• The primary benefit of IPmux-16
is allowing transparent E1/T1 and
E3/T3 connectivity over Layer 2/3
packet networks, both in carrier
and enterprise environments.
• IPmux-16 converts data streams of
up to sixteen E1/T1 or up to two
E3/T3, or up to two CT3 ports and
converts them into packets for
transmission over the network.
The addressing scheme of these
packets is IP-based. The packets
are transmitted via the Ethernet
modules to the network. A remote
TDMoIP gateway converts the IP
packets back to TDM traffic.
• 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 RAD’s IPmux-1E
IPmux-11, IPmux-14, IPmux-8,
Megaplex ML-IP, Kilomux
KML.11, and other third-party
products that implement the
TDMoIP protocol.
• 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 an NMS.
PERFORMANCE
• IPmux-16 achieves end-to-end
processing delay as low as 1.7 msec,
using high-performance buffering
and forwarding techniques.
• 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 the
TDMoIP traffic for delay-sensitive
applications.
• Assigned, IANA-registered UDP
socket number for TDMoIP
simplifies flow classification
through switches and routers.
• 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
20 msec for E3/T3
42 msec for internal T1 in CT3.
QoS SUPPORT
• IPmux-16 supports VLAN tagging
and priority labeling according to
802.1p&Q.

separated by applying a dedicated
VLAN tag to every TDMoIP

OPERATION MODES
• Two types of service are offered:
Unframed: Full E1/T1 or E3/T3
circuits are transparently
extended across the network,
regardless of framing structure.
Framed: IPmux-16 can be
configured on a per-timeslot
basis for fractional E1/T1 services
over the packet network. CAS 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
bundle cross-connect.
TIMING
• IPmux-16 maintains
synchronization between TDM
devices by deploying advanced
clock distribution mechanisms.
The clocking options are:
Internal: The IPmux-16 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: An optional station
clock port can be used to
synchronize E1/T1 interfaces.
ETHERNET MODULES
• Two Ethernet modules can be
installed in the IPmux-16 chassis,
providing the uplink to the packet
network.
• Ethernet link redundancy to the
network is supported when
IPmux-16 is equipped with two
Ethernet modules.
• Each module supports a single
10/100BaseT or 100BaseFx port.
• The network Ethernet modules
re-order packets arriving from the
network in the wrong order.
E1 AND T1 MODULES
• Each E1 or T1 module features
either four or eight E1 or T1
interfaces, which enable
connectivity to any standard E1 or
T1 device.
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/local loopback tests are all
supported. Standard E1/T1 alarms
are transmitted end-to-end.
CHANNELIZED T3 MODULES
• A channelized T3 (CT3) module
converts T3 service signals into
28 unframed T1 streams, and each
T1 stream into IP frames that are
sent via a Fast Ethernet network.
E3 AND T3 MODULES
• Each E3 or T3 module features 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/local loopback tests are
supported. Standard E3 or T3 alarms
are transmitted end-to-end.
POWER SUPPLY
• Modular hot-swappable power
supplies of the chassis support
carrier environments. The
maximum power supplied by one
unit is 75W with maximum power
consumption of 57W.
DIAGNOSTICS & MANAGEMENT
• IPmux-16 supports remote and
local loopback testing. End-to-end
alarm generation and end-to-end
AIS indication are also provided. If
a local E1/T1 port receives AIS, it is
reported to the remote port via the
Ethernet/IP network. If a local
Ethernet port is disconnected, an
AIS indication is generated both in
the local and the remote devices.
• 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.

monitored:
Locally via an ASCII terminal
Remotely via Telnet or
SNMP-based management
software (RADview Service
Center TDMoIP).
• 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 generate
SNMP traps.
SPECIFICATIONS
• IPmux-16 can be configured and
• RADview Service Center TDMoIP
network management application
provides TDMoIP service and
manages the TDMoIP devices via
a user-friendly graphical display
that allows monitoring and
configuring multiple IPmux
devices. Fault isolation, statistics
and events gathering are available.
The Service Center’s intuitive
GUI, "point-and-click"
functionality and easy-to-follow
wizards increase the efficiency
and accuracy of the service
provisioning process.
• An internal built-in test (BIT) is
performed after power-up. The
results of the test are displayed at
the local terminal.
• Software download is supported
locally using XMODEM, or
remotely, using TFTP protocols.
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.
