Handling Energized Products
General Safety Practices
Do not touch or tamper with the power supply when the power cord is connected. Line voltages may
be present inside certain products even when the power switch (if installed) is in the OFF position or a
fuse is blown. For DC-powered products, although the voltages levels are usually not hazardous,
energy hazards may still exist.
Before working on equipment connected to power lines or telecommunication lines, remove jewelry
or any other metallic object that may come into contact with energized parts.
Unless otherwise specified, all products are intended to be grounded during normal use. Grounding is
provided by connecting the mains plug to a wall socket with a protective earth terminal. If an earth lug
is provided on the product, it should be connected to the protective earth at all times, by a wire with a
diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in earthed racks
and cabinets.
Always make the ground connection first and disconnect it last. Do not connect telecommunication
cables to ungrounded equipment. Make sure that all other cables are disconnected before
disconnecting the ground.
Connection of AC Mains
Make sure that the electrical installation complies with local codes.
Always connect the AC plug to a wall socket with a protective ground.
The maximum permissible current capability of the branch distribution circuit that supplies power to
the product is 16A. The circuit breaker in the building installation should have high breaking capacity
and must operate at short-circuit current exceeding 35A.
Always connect the power cord first to the equipment and then to the wall socket. If a power switch is
provided in the equipment, set it to the OFF position. If the power cord cannot be readily
disconnected in case of emergency, make sure that a readily accessible circuit breaker or emergency
switch is installed in the building installation.
Connection of DC Mains
Unless otherwise specified in the manual, the DC input to the equipment is floating in reference to the
ground. Any single pole can be externally grounded.
Due to the high current capability of DC mains systems, care should be taken when connecting the DC
supply to avoid short-circuits and fire hazards.
DC units should be installed in a restricted access area, i.e. an area where access is authorized only to
qualified service and maintenance personnel.
Make sure that the DC supply is electrically isolated from any AC source and that the installation
complies with the local codes.
The maximum permissible current capability of the branch distribution circuit that supplies power to
the product is 16A. The circuit breaker in the building installation should have high breaking capacity
and must operate at short-circuit current exceeding 35A.
Before connecting the DC supply wires, ensure that power is removed form the DC circuit. Locate the
circuit breaker of the panel board that services the equipment and switch it to the OFF position. When
connecting the DC supply wires, first connect the ground wire to the corresponding terminal, then the
positive pole and last the negative pole. Switch the circuit breaker back to the ON position.
A readily accessible disconnect device that is suitably rated and approved should be incorporated in
the building installation.
Connection of Data and Telecommunications Cables
Data and telecommunication interfaces are classified according to their safety status.
The following table lists the status of several standard interfaces. If the status of a given port differs from
the standard one, a notice will be given in the manual.

up to 30 VAC or 60 VDC.
TNV-1 Telecommunication Network Voltage-1:
Ports whose normal operating voltage is within the
limits of SELV, on which overvoltages from
telecommunications networks are possible.
Ports whose normal operating voltage exceeds the
limits of SELV (usually up to 120 VDC or telephone
ringing voltages), on which overvoltages from
telecommunication networks are not possible. These
ports are not permitted to be directly connected to
external telephone and data lines.
TNV-3 Telecommunication Network Voltage-3:
Ports whose normal operating voltage exceeds the
limits of SELV (usually up to 120 VDC or telephone
ringing voltages), on which overvoltages from
telecommunication networks are possible.
Always connect a given port to a port of the same safety status. If in doubt, seek the assistance of a
qualified safety engineer.
Always make sure that the equipment is grounded before connecting telecommunication cables. Do
not disconnect the ground connection before disconnecting all telecommunications cables.
Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables.
Extra caution should be exercised during thunderstorms.
When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The
earthing and bonding of the ground connections should comply with the local codes.
The telecommunication wiring in the building may be damaged or present a fire hazard in case of
contact between exposed external wires and the AC power lines. In order to reduce the risk, there are
restrictions on the diameter of wires in the telecom cables, between the equipment and the mating
connectors.
Caution
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cords.
Attention
Pour réduire les risques s’incendie, utiliser seulement des conducteurs de
télécommunications 26 AWG ou de section supérieure.
Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only. In such
cases, a notice will be given in the installation instructions.
Do not attempt to tamper with any carrier-provided equipment or connection hardware.
Electromagnetic Compatibility (EMC)
The equipment is designed and approved to comply with the electromagnetic regulations of major
regulatory bodies. The following instructions may enhance the performance of the equipment and will
provide better protection against excessive emission and better immunity against disturbances.
A good earth connection is essential. When installing the equipment in a rack, make sure to remove all
traces of paint from the mounting points. Use suitable lock-washers and torque. If an external
grounding lug is provided, connect it to the earth bus using braided wire as short as possible.
The equipment is designed to comply with EMC requirements when connecting it with unshielded
twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially for
high-rate data. In some cases, when unshielded wires are used, ferrite cores should be installed on
certain cables. In such cases, special instructions are provided in the manual.
Disconnect all wires which are not in permanent use, such as cables used for one-time configuration.
The compliance of the equipment with the regulations for conducted emission on the data lines is
dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal conversion loss
(LCL).
Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary
protection against surges on the data lines. Primary protectors should be provided in the building
installation.
The equipment is designed to provide adequate protection against electro-static discharge (ESD).
However, it is good working practice to use caution when connecting cables terminated with plastic
connectors (without a grounded metal hood, such as flat cables) to sensitive data lines. Before
connecting such cables, discharge yourself by touching earth ground or wear an ESD preventive wrist
strap.

connecting such cables, discharge yourself by touching earth ground or wear an ESD preventive wrist
strap.

Quick Start Guide
1. Setting Jumpers - IPmux-1E ISDN Version Only
The IPmux-1E ISDN version contains jumpers for Phantom Feed. Other
IPmux-1/1E models do not require jumper configuration.
To set the IPmux-1E ISDN-S module jumpers:
If necessary, change the settings in accordance with the specific requirements of
your application:
• ENA – enable Phantom Feed
• DIS – disable Phantom Feed.
The Phantom Feed ENA/DIS setting influences the IPmux-1E BRI operation mode.
When Phantom Feed is disabled, the S-interface can be configured (through
software) to the TE or NT mode. When Phantom Feed is enabled, only the NT
mode is possible.
2. IPmux-1/1E Operation
To operate the IPmux-1/1E:
1. Power up the IPmux-1/1E unit.
2. Connect an ASCII terminal to IPmux-1/1E control port (IPmux-1/1E default
setting: 19200, N, 8, 1).
3. Verify IPmux-1/1E startup by one of the following:
From the ASCII terminal, verify that the Self-Test has ended successfully.
Check the RDY LED on the on the left side of the front panel of the unit.
4. Connect the Ethernet link cable to the network port (connect an Ethernet link
to the user port if the model includes one) and check the Sync LED.
5. Connect TDM cables to the TDM port.
6. Log in to the system software.

Overview 1-5
Chapter 1 Introduction IPmux-1/1E Installation and Operation Manual
ISDN BRI
IPmux-1E has 4-ports, S-interface only. Each port can be configured as either NT
or TE (Network/User) by jumper and software; NT or TE is configured per device.
IPmux-1E can be configured to 1, 2, 3 or 4 active ports.
IPmux-1E works in transparent mode (no termination/compression of the BRI “D”
channels). It operates opposite a Megaplex unit, as a concentrator in transparent
mode, or opposite another IPmux-1E with ISDN BRI ports.
FXS/FXO/E&M
IPmux-1E has 4 FXS/FXO/E&M interface ports for POTS connection. An IPmux unit
with an E1/T1 CAS interface can groom FXS/FXO/E&M channels from the remote
sites. IPmux-1E analog options interwork with Megaplex analog and E1/T1
modules via the Megaplex TDMoIP main link (ML-IP)
IP
The data stream coming from the E1 or T1 port is converted into IP packets that
are transported over the Fast Ethernet port, and vice versa.
Note
TDM bytes are encapsulated in a UDP frame that runs over IP and over Ethernet.
The number of TDM bytes in an IP frame is configurable for throughput/delay
tradeoff.
Each device has a single IP address (Host IP). A configurable destination IP address
is assigned to the IP packets. IP ToS field support can be configured for IP Level
Priority. In Redundancy Mode, a secondary IP Address is used for the backup
bundle; this device IP Address defines a response for a ping, but not for
management.
Ethernet Ports
IPmux-1/1E is available with two Ethernet ports (user and network ports). The
optional user Ethernet port is used for user LAN connectivity/access, in addition to
the TDM service connectivity.
The Ethernet ports work in either transparent bridge mode or in a second mode
that enables user port rate limiting.
The Ethernet network port can be either UTP or fiber. The Ethernet user port is
UTP only.
• Fiber option – standard 100BaseFx full-duplex port (see Table 1-1).
• UTP option – A standard 10/100BaseT half/full-duplex port with
auto-negotiation support. If auto-negotiation is disabled, Ethernet mode should
be configured.
Half-duplex operation in the IPmux-1/1E network port is not recommended,
because collisions and backoffs cause large delay variation and may exceed the
delay variation buffer tolerance at the receiving end, causing buffer underflows and
errors to occur.

Chapter 1 Introduction IPmux-1/1E Installation and Operation Manual
QoS
QoS supports:
• Labeling IP level priority (ToS/Diffserv) for TDMoIP packets
• VLAN tagging and priority labeling according to IEEE 802.1p&q for TDMoIP
packets.
The user can configure the ToS (Type of Service) of the outgoing TDMoIP packets.
This allows an en-route Layer 3 router or switch, which supports ToS, to give
higher priority to IPmux-1/1E TDMoIP traffic for delay-sensitive and secure
applications. IPmux-1 allows you to configure the WHOLE ToS byte field, since
different vendors may use different bits to tag packets for traffic prioritization.
This also enables operation according to various RFC definitions (for example RFC
2474, RFC 791). The user can also configure VLAN priority bits for
Level 2 Priority.
Timing
IPmux-1 maintains synchronization between TDM devices by deploying advanced
clock distribution mechanisms.
Note
Available timing modes are:
• Loopback
• Adaptive
• Internal Clock
• External Clock.
For more details see Timing Modes in Section 1.3.

Operation Modes
Static Mode
When the timeslot allocation is static and no activity is detected, the payload can
be efficiently encoded using a constant bit rate.
The TDMoIP payload consists of between one and thirty 48-octet subframes. The
number of subframes is pre-configured and typically chosen according to latency
and bandwidth constraints.
Dynamic CAS Mode
When timeslots are dynamically allocated, and CAS can be detected for
bandwidth conservation, the payload can be efficiently encoded using a variable
bit rate.

E1/T1
CESoIP Mode
In general, when the timeslot allocation is static and no activity is detected, the
payload can be efficiently encoded using a constant bit rate.
The CESoIP payload size is based on the packetization delay (in msec); the
minimum size is 1 msec, and increases in steps of 1 msec.
1-10 Functional Description
IPmux-1/1E Installation and Operation Manual Chapter 1 Introduction
E1/T1
This section describes the IPmux-1 E1/T1 operation modes, which are:
• Unframed – valid for static and CESoIP/E1
• Fractional – valid only for static and CESoIP
• Fractional with CAS –valid only for static and dynamic CAS .
Unframed (Transparent)
In the transparent mode, the incoming bit stream from each channel (regardless of
framing) is converted into IP over Ethernet frames. This option provides clear
channel end-to-end service (unframed).
Fractional
In the fractional mode, the incoming bit stream is regarded as a sequence of
n x 64 kbps channel groups (according to framing). Each predefined group of
channels is converted into a structure block. The structure block is packetized into
IP frames and transmitted.
This mode allows transmission of several selected timeslots without the whole E1
or T1 frame, as in transparent mode.
Note
Use Fractional mode when grooming ISDN BRI channels from a remote IPmux-1E
unit.
Note
Fractional with CAS
In the fractional-with-CAS mode, the structure block (as described under
Fractional Operation Modes, above) also includes Channel Associated Signaling
(CAS). The relevant portion of the signaling channel is packetized and sent to the
destination.
Use Fractional with CAS mode when grooming FXS/FXO/E&M channels from a
remote IPmux-1E unit.
ISDN BRI
The section describes the IPmux-1E ISDN BRI S-interface operation modes, which
are:
• TE mode
• NT mode.
The selected mode applies to all 4 channels. The NT or TE mode is determined by
phantom feeding and software setting, which is enabled/disabled by jumpers
located on the ISDN BRI card (see Chapter 2).
TE Mode
All four channels are configured in TE (Terminal Equipment) as defined in I.430.
NT Mode
All four channels are configured in NT (Network Termination) as defined in I.430.
TE Deactivation is not used in NT mode, and Layer 1 is always in active.
Functional Description 1-11
Chapter 1 Introduction IPmux-1/1E Installation and Operation Manual
Note
If the jumpers enable phantom feeding, the TE mode cannot be selected as the
IPmux-1E operation mode. If phantom feeding is disabled, both NT and TE are valid
options.
FXS/FXO/E&M
The section describes the FXS/FXO/E&M operation modes, which are:
• E1 mode
• T1-D4 mode
• T1 ESF mode.
The IPmux-1E FXS/FXO/E&M operation modes allow IPmux to work opposite E1,
T1-D4, or T1-ESF. Two parameters are set internally when choosing one of the
options:
• A-Law/µ-Law
A-Law when E1 mode is selected
µ-Law is used in PCM CODEC when T1 (D4 or ESF) is selected.
• E1, T1-D4, and T1-ESF with CAS are structured differently in the TDM ↔IP
interworking function. A different structure must be used when working
opposite each one.
Timeslot Assignment in a Bundle
A bundle is a group of timeslots associated with a specific E1 or T1 channel.
IPmux-1/1E places individual or multiple TDM timeslots (up to 31 timeslots) into
bundles with a single IP address destination.
ISDN BRI
The timeslot (TS) assignment in a bundle for IPmux-1E with ISDN BRI (when
working opposite IPmux with E1/T1 or Megaplex) is assigned as follows:
First Channel
B1
Figure 1-10. Timeslot Assignment in a Bundle, for IPmux-1E/ISDN
As shown in Figure 1-10, the four ISDN BRI channels consume 12 timeslots in the
bundle. The E1/T1 IPmux should work in framed mode (no CAS).
B2 D
MSB Bits 7, 6 contain
D channel information
Second Channel

B2 D
MSB Bits 7, 6 contain

…
The three TS groups in the bundle are assigned according to ISDN BRI channel
numbers; the first group is assigned to the lowest ISDN BRI channel that is
enabled, etc.
1-12 Functional Description
IPmux-1/1E Installation and Operation Manual Chapter 1 Introduction
FXS/FXO/E&M
The TS assignment in a bundle with analog (FXS/FXO/E&M) is straightforward. Each
timeslot in a bundle is assigned to a specific analog channel according to analog
channel numbers; the first timeslot is assigned to the lowest analog channel that is
configured, etc.
Note
The E1/T1 TDMoIP gateway that works opposite the analog channels should work in
Framed with CAS mode.
Testing
Diagnostic capabilities include E1/T1 or ISDN BRI S local and remote loopback
tests for rapid localization of faults. The E1/T1 or ISDN BRI S channel can be
looped locally, toward the line, or toward the remote end (see Chapter 4 for more
information).
Remote Loopback and Tone Injection are available for the FXS/FXO/E&M port.
Timing Modes
The E1/T1 Tx clock, or ISDN/FXS PCM clock, can operate in several timing modes
to provide maximum flexibility for connecting the IPmux-1/1E E1, T1, ISDN or
FXS/FXO/E&M channels.
Note
Each of the clocks must be configured correctly on both the Receive and Transmit
ends to ensure proper operation and prevent pattern slips (see Figure 1-11,
Figure 1-13, and Figure 1-14).
E1/T1
The E1/T1 available Tx modes are:
• Loopback Timing – the E1/T1 Tx clock is derived from the E1/T1 receive (Rx)
clock.
• Adaptive Timing – in this mode, the E1 or T1 Tx clock is regenerated using the
Adaptive method. In this method, the fill level of the buffer receiving packets is
monitored. If the buffer begins to overfill, the regenerated Tx clock frequency
increases to avoid overflow. If the buffer begins to empty, the Tx clock (toward
the TDM device) decreases to avoid underflow.
• Internal Clock Timing – in this mode, the Tx clock is received from an internal
oscillator.
• External Clock Timing – in this mode the Tx clock is taken from the external
clock input (Ordering option). The external clock port also outputs the input
clock signal to allow connection to other units, if needed.
In Adaptive Timing mode the regenerated clock is subject to network Packet Delay
Variation and may not comply with jitter and wander specifications.
Functional Description 1-13
Chapter 1 Introduction IPmux-1/1E Installation and Operation Manual
ISDN/FXS/FXO/E&M
The available timing modes for the PCM clock are:
• Loopback Timing – available only when IPmux-1E ISDN BRI is configured as
TE (not available in ISDN BRI NT mode or for FXS/FXO/E&M interface). In this
mode the PCM clock is derived from Channel 1. It is recommended not to
deactivate Channel 1 while it is in loopback clock so that data will not be
damaged. If Channel 1 is disconnected or deactivated (by the NT side), the
PCM clock will change to Internal clock and a momentary disruption will
occur to the other channels (2,3,4), if they are active.
• Adaptive Mode – the clock is regenerated using the Adaptive method, where
the rate of arriving packets is used to regenerate the clock (see E1/T1, above).
• Internal Mode – the clock is received from an internal oscillator.
Network Timing Schemes
The following paragraphs describe typical timing schemes and the correct timing
mode settings for achieving end-to-end synchronization.
External Network Timing
When the edges of the network are synchronized by an external network clock
source, all the IPmux-1 units should be configured to work in loopback timing
mode (see Figure 1-11). This topology enables any-to-any connectivity.

Frame Format
The Ethernet frame sent by the IPmux-1 is a UDP datagram that transfers E1/T1
payload bytes over IP over Ethernet (UDP payload + UDP header + IP header +
Ethernet header). The UDP payload size depends on the connection mode:
• Static mode: The UDP payload size is equal to TDM bytes per frame
(TDM bytes/frame configuration).
• Dynamic CAS mode: The maximum UDP payload size depends on the
number of configured
time slots and is equal to:
Note
[(TSA + 4) x (number of configured
timeslots)] + 4]
where TSA = Active timeslot bytes in frame
Active timeslot bytes in frame are the number of bytes per timeslot that are passed
per Ethernet frame.
An Active timeslot is one where a call is detected by monitoring CAS.
The UDP payload size is not fixed–it depends on the number of active time
slots:
[(TSA + 4) x (number of active
timeslots)] + 4]
• CESoIP mode: The UDP payload size is equal to:
[(Configured Packet Delay) x (number of configured
timeslots) x 8] + 12
Table 1-2 specifies the structure of the different headers, special fields, and the
payload in the Ethernet packet.

Packet Delay Variation
Packets are transmitted at set intervals. Packet Delay Variation is the maximum
deviation from the nominal time the packets are expected to arrive at the far end
device. IPmux-1 has a buffer that compensates for the deviation from the expected
packet arrival time to prevent IPmux-1 buffers from emptying out or overflowing.
Packet Delay Variation is an important network parameter. Large PDV (exceeding
the jitter buffer configuration) will cause receive buffer underflows and errors at
the TDM level (see Figure 1-17).
To compensate for large PDV, configure the PDVT (jitter) buffer to a higher value.
1-18 Functional Description
IPmux-1/1E Installation and Operation Manual Chapter 1 Introduction
g
Packets Leaving IPmux-1
Packets Arriving
PDVT (Jitter) Buffer
IPmux-1 is equipped with a Packet DVT (Delay Variation Tolerance) buffer. The
PDVT buffer or jitter buffer is filled by the incoming IP packets and emptied out to
fill the TDM stream. The buffer begins to empty out only after it is half full in order
to compensate for packet starvation from the Ethernet side. The time it takes for
half of the buffer to empty out is the maximum DVT time. Delay Variation
Tolerance is configurable. The PDVT (jitter) buffer is designed to compensate for
packet delay variation caused by the network + intrinsic PDV.
It supports a delay variation of up to 300 ms for E1 or T1 in static or dynamic CAS
modes, and up to 127 ms in CESoIP mode.
PDV
Figure 1-17. Packet Delay Variation
t
t
Note
PDVT Buffer Effect on Delay
The PDVT buffer is on the TDM path; it adds to the total end-to-end delay (see
delay calculation, below).
Intrinsic PDV in Static Mode
If TDM bytes/frame is greater than 48, there is an intrinsic delay variation (intrinsic
PDV). The intrinsic PDV introduced by the module is a function of n>1 in
TDM bytes/frame configuration as follows:
I.PDV (ms) = [(n-1) x 1000) / (frames per second × n]
where n =
ured
48
To configure jitter buffer depth:
The estimated or measured PDV introduced by the network + intrinsic PDV
(if it exists) introduced by the module as a result of configuring the
TDM bytes / frame > 48.
For a bundle that contains a few timeslots (i.e. 1 to 3) the minimal jitter buffer
should be 6 ms.

Functional Description 1-19
Chapter 1 Introduction IPmux-1/1E Installation and Operation Manual
Intrinsic PDV in Dynamic CAS Mode
I.PDV (ms) = active time slot bytes in frame X 0.125
Active time slot bytes in frame is the number of bytes per active time slot that will
be sent on every frame transmitted over the Ethernet.
Intrinsic PDV in CESoIP Mode
The value of the packet delay configuration is user-defined.
Ethernet Throughput
Higher throughput reduces the IP/Ethernet overhead segment of the total packet
and thus can significantly reduce the total Ethernet throughput.
On the other hand, packetization delay and intrinsic packet delay variation (PDVT)
are increased; this contributes to a higher end-to-end delay. This effect can be
small and negligible when a full E1 (or many timeslots) are transferred, but can be
very significant when few timeslots are transferred. In this case, the packetization
delay and the intrinsic PDV when configuring a large value of TDM bytes/frame
can be very large and may exceed the maximum PDVT (jitter) buffer on the
receiving end.
Note
Ethernet Throughput in Static Mode
Configuring the TDM bytes per frame (TDM bytes/frame) parameter can reduce
Ethernet throughput (bandwidth or traffic traveling through the Ethernet). This
parameter controls the number of TDM bytes encapsulated in one frame.
The TDM bytes/frame parameter can be configured to n x 48 bytes where n is an
integer between 1 and 30.
To calculate Ethernet throughput and intrinsic PDV as a function of
TDM bytes/frame:
Ethernet load (bps) =
[(frame overhead (bytes) + TDM bytes/frame) x 8] x frames/second
Frame overhead = Ethernet overhead + IP overhead = 46 bytes
The frame overhead does not include:
• Preamble field: 7 bytes
• SFD field: 1 byte
• Interframe gap: 12 bytes
• VLAN field (when used): 4 bytes.

Ethernet Throughput in Dynamic CAS Mode
Configuring the active time slot bytes parameter can reduce Ethernet throughput.
This parameter controls the number of TCM bytes encapsulated per time slot in a
frame. The range is 24 to 64 bytes.
A large number of time slots and a large active time slot bytes size can surpass the
maximum Ethernet frame size.
In dynamic CAS mode the throughput is variable, depending on the active time
slots as defined by the ABCD CAS bits.

• Packets are duplicated.

The ability to correct problems of reordering is only supported for odd values of
payload, i.e. 1, 3, 5, 7, …, 29.

When a destination IPmux is lost, the traffic load that is transmitted to that IPmux
is significantly decreased (several packets per second per connection). The IPmux
starts transmitting at full rate only when it detects an IPmux at the remote side.
OAM Connectivity is used to detect a valid connection (the remote IPmux will
confirm it recognizes the connection and that it is enabled). It prevents flooding by
a handshake.
The control packets are run over a unique bundle number that is used for this
purpose. The control packets have the same VLAN ID and TOS of the originating
connection. The control packet uses the TDMoIP UDP number.
OAM Connectivity can be set to Disable/Enable.
Note
For control packets, the UDP check sum is not calculated nor checked.
End-to-End Alarm Generation
An end-to-end alarm generation mechanism exists in IPmux-1 to facilitate the
following alarms:
Unframed AIS is transmitted toward the near-end PBX in event of:
• Far-end LOS, AIS
• PDVT underflow/overflow.
Framed Timeslot/CAS configurable alarm pattern is transmitted toward the
near-end PBX in event of:
• Far-end LOS, LOF, AIS
• PDVT underflow/overflow.

Ethernet User Port
The Ethernet user port allows a user to aggregate both TDMoIP traffic and his
private network LAN traffic to a single Ethernet network connection without
requiring an access switch. This is a cost effective solution for MTU or small office
applications. A rate limiter to restrict user port traffic is supported.
IPmux-1/1E contains an internal switch where one of its ports is connected to a
TDMoIP interworking function, another external switch port is used as the user
port, and the third is used as an Ethernet network port.

Priority is always given to TDMoIP packets inside the internal switch.
Internal Switch Operation Modes
IPmux-1/1E offers a user LAN port in addition to the LAN port on the network
side. The device performs switching at level 2. The switch supports both
transparent bridging and VLAN-aware bridging. The switch supports rate limiting of
traffic going from the user port to the network port. It supports up to 12K MAC
addresses (depending on their values and the order in which they are learned).
The switch modes are described later in this section. They are:
• Basic mode
• User Tagged mode
• User Untagged mode
• Rate mode
• Rate + User Tagged mode.
• Rate + User Untagged mode
Rate Limiter Option
In this option a rate limiter is available to limit user port traffic. This feature is
valuable when a limited bandwidth DSL modem, for example, is used to extend
the Ethernet link (generally when the Ethernet link rate is limited/shaped to a lower
rate after IPmux). In this case TDMoIP packets will be dropped in the modem
even if it was prioritized at the IPmux internal switch. This is prevented by limiting
the user port to actual link rate minus TDMoIP bandwidth. The rate limiter can
limit user traffic at 50 kbps steps up to 5 Mbps and in 1 Mbps steps from 5 Mbps
to 100 Mbps.

Dynamic Host Configuration Protocol (DHCP) is a TCP/IP protocol that enables
PCs and workstations to get temporary or permanent IP Addresses (out of a pool)
from centrally administered servers.
DHCP is based on RFC 1531 and RFC 1533.
Lease Length
You can request an IP Address for an infinite period of time (Infinite Lease);
however, you must accept the time period that is determined by the server, even if
it is different from what you requested.

IPmux-1/1E Installation and Operation Manual Chapter 1 Introduction
Manager Option
The server may send IPmux-1/1E a Manager configuration via the DHCP option
field:
• Manager IP - Option 200 (type IP Address)
• VLAN ID - Option 201 (type long)
• VLAN Priority - Option 202 (type byte).
When IPmux-1/1E requests a Manager configuration from the server, there may be
many replies. The device accepts the offer that includes a Manager Option.
If the reply does not include a Manager Option, IPmux-1/1E waits three seconds
for another reply from the server. If no replies have Manager Option, the device
accepts the first offer.

Introduction 2-1
Chapter 2 Installation IPmux-1/1E Installation and Operation Manual
2.2 Site Requirements and Prerequisites
Install AC-powered IPmux-1/1E units within 1.5m (5 feet) of an easily-accessible
grounded AC outlet capable of furnishing the required supply voltage, in the range
of 100 to 240 VAC.
DC-powered IPmux-1 units require a 48 VDC power source. The positive pole can
be earthed.
The maximum permissible current capability of the branch distribution circuit that
supplies power to the product is 16A.
Caution
The DC power source must be isolated from the mains supply by double or
reinforced insulation. A suitable fuse or a circuit breaker (16A) should be
integrated in the negative power-supply line.
Allow at least 90 cm (36 inches) of frontal clearance for operator access. Allow at
least 10 cm (4 inches) clearance at the rear of the unit for cable connections. Make
sure that the ventilation holes are not blocked.

2.4 Equipment Needed
IPmux-1/1E needs no special tools for installation. A screwdriver is necessary when
mounting IPmux-1/1E in a 19-inch rack.
2.5 Installation and Setup
Setting Jumpers
IPmux-1
IPmux-1 internal jumpers and switches do not need to be configured by the user.
Therefore, removing the product cover is not required.
IPmux-1E
The IPmux-1E FXS/FXO/E&M version needs NO user internal jumper
configuration.
The IPmux-1E ISDN version contains jumpers that must be set for phantom feed
(see Figure 2-1). Open the case and verify the positions of internal jumpers before
proceeding to the IPmux-1E installation, which is explained below.
To open the IPmux-1E case:
1. Disconnect all the cables connected to the IPmux-1E.
2. Release the cover screws at the rear panel (one is near the POWER connector).
3. Slide the IPmux-1E top cover by pulling it straight out.
To set the IPmux-1E ISDN-S module jumpers:
If necessary, change the settings in accordance with the specific requirements of
your application:
• ENA – enable phantom feed
• DIS – disable phantom feed
The phantom feed ENA/DIS setting influences the IPmux-1E ISDN BRI operation
mode. When phantom feed is disabled, the S-interface can be configured (through
software) to the TE or NT mode. When phantom feed is enabled, only the NT
mode is possible.
Installation and Setup 2-3
Chapter 2 Installation IPmux-1/1E Installation and Operation Manual
Only qualified and authorized service personnel should have access to the
inside of the unit.
Warning
Caution
Disconnect the unit from the power line and from all the cables before
removing the cover.
Line voltages are present inside IPmux-1/ 1E when it is connected to power.
Moreover, under certain external fault conditions, dangerous voltages may
appear on the lines connected to IPmux-1/1E.
Any adjustment, maintenance, and repair of the opened device under voltage
should be avoided as much as possible and, when inevitable, should be
carried out only by a skilled technician who is aware of the hazards involved.
Capacitors inside the device may still be charged even after it has been
disconnected from its source of power.
The IPmux-1/1E contains components sensitive to electrostatic discharge (ESD). To
prevent ESD damage, avoid touching the internal components, and before moving
jumpers, touch the IPmux-1/IPmux-1E rear panel.
After completing the internal settings, reinstall the top cover as follows:
1. Position the IPmux-1/1E case on a flat, clean surface.
2. Slide the cover into the slots from the rear panel, and set the cover in place.
3. Fasten the cover to the rear panel with the locking spring screws (one is near

2-10 Installation and Setup
IPmux-1/1E Installation and Operation Manual Chapter 2 Installation
DC Power Connection
A DC power supply option is available to be ordered for IPmux-1 only (not
available for IPmux-1E. For information about connecting the DC power supply
refer to the DC Power Supply Connection Supplement.
Due to the high current capability of DC mains systems, care should be taken
when connecting the DC supply, in order to avoid short-circuits and fire
hazards.
Warning
DC units should be installed in a restricted access area, i.e., an area where
access is authorized only to qualified service and maintenance personnel.
Make sure that the DC supply is electrically isolated from any AC source, and
that the installation complies with the local codes.
The maximum permissible current capability of the branch distribution circuit
that supplies power to the product is 16A.
Before connecting the DC input plug, ensure that power is removed from the
DC circuit. Locate the circuit breaker of the panel board that services the
equipment, and switch it to the OFF position. When connecting the other end
of the DC cable, first connect the ground wire, then the position pole, and
lastly the negative pole. Switch the circuit breaker back to the ON position.
A readily accessible disconnect device that is suitably rated and approved
should be incorporated in the building installation.

Troubleshooting and
Diagnostics
This chapter describes how to:
• Detect errors
• Troubleshoot problems
• Perform diagnostic tests.
4.1 Error Detection
Using Front Panel LEDs
LED indicators on the front panel IPmux-1/1E indicate the operating status of the
module. The LED indicators are described in Chapter 3 of this manual.
Working with the Alarm Buffer
IPmux-1/1E maintains an Event Log File. All events are time-stamped. The user can
view the contents of the Event Log File via an ASCII terminal or a Telnet Session.
The user can also clear the contents of the Log File.
Table 4-1 presents the event types that appear on the Event Log File alphabetically,
as well as the actions required to correct the event (alarm) indication.
To correct the reported problem, perform corrective actions in the given order
until the problem is corrected. If the problem cannot be fixed by carrying out the
listed actions, IPmux-1/1E MUST be checked by the authorized technical support
personnel.
