Chapter 1
Introduction

1.1 Overview

IPmux-1/1E offers a solution for extending traditional E1/T1, ISDN, or POTS TDM
services transparently over the widely deployed IP networks. The device converts
the data stream coming from its user ports into configurable sized IP packets that
are extended over the Fast Ethernet port and vice versa. IPmux-1/1E offers
end-to-end synchronization for voice applications. IPmux-1/1E also offers large
buffers to compensate for the delay variation inserted by the network. The device
can be used to extend E1/T1 or ISDN/POTS circuits over IP networks for
Metropolitan Area Network applications. IPmux-1/1E also features a Fast Ethernet
user port for data (Ethernet) connectivity to the IP/Ethernet network. Management
is performed locally by a terminal, or remotely via Telnet or SNMP.

Versions

IPmux-1 has a single E1/T1 port.

IPmux-1E offers one of the following options:

• 4 BRI – a card with 4 ISDN standard S-interfaces

• 4 FXS – a card with 4 FXS ports

• Optional user Ethernet port.

The IPmux family implements TDMoIP technology to carry TDM transport over IP.
IPmux-1E BRI channels are transported as TDM timeslots, while the Analog FXS
channels are digitized and carried as fractional E1/T1 with CAS.

• IPmux-1 with E1 interface

− Balanced line with an RJ-45 connector

− Unbalanced line with a mini-coaxial connector (TBNC)

• IPmux-1 with T1 interface – Balanced with an RJ-45 connector

• IPmux-1E with ISDN BRI interface –4 ISDN ‘S’ RJ-45 connectors

• IPmux-1E with FXS interface – 4 Analog ‘FXS’ RJ-11 connectors

Ph:727-398-5252/Fax:[phone]

www.bestdatasource.com

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 D channels).
It operates opposite IPmux with E1/T1 and a Megaplex unit as a concentrator in
transparent mode or opposite another IPmux-1E with ISDN BRI ports.

FXS

IPmux-1E has 4 FXS interface ports for POTS connection. A central IPmux unit
with an E1/T1 CAS interface can groom FXS channels from the remote site.

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.

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.

Ethernet User Port

IPmux-1E has an optional user port for user LAN connectivity/access as well as
TDM services connectivity. A transparent bridging mode is supported
(user/network Ethernet port) and a second mode which enables user port rate
limiting.

Ethernet Physical Port

IPmux-1/1E is available with Ethernet ports (user or network port). The Ethernet
network port can be either UTP or fiber. The Ethernet user port is UTP only.

• UTP option – A standard 10/100BaseT half/full duplex port with

auto-negotiation support. If auto-negotiation is disabled, IPmux-1 capabilities
can be configured to 100BaseT – full duplex, 100BaseT – half duplex,
10BaseT – full duplex, or 10BaseT – half-duplex. Half-duplex operation in
IPmux-1 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.

Overview 1-7

• Fiber option – standard 100BaseF full duplex port (see Table 1-1).

• Unframed E1/T1 over UDP over IP over Ethernet

• Fractional E1/T1 over UDP over IP over Ethernet

• Fractional E1/T1 with CAS over UDP over IP over Ethernet.

IPmux-1E with BRI can operate in two modes:

• NT mode

• TE mode.

IPmux-1E with FXS can operate in three modes:

• E1 mode

• T1 mode D4 mode

• T1 ESF mode.

Note

IPmux E1/T1 working opposite IPmux-1E with BRI ports should work in Fractional
E1/T1 mode (no CAS). When working opposite IPmux-1E with FXS, use E1/T1 CAS
mode.

QoS

QoS support:

• Labeling IP level priority (ToS) 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 you to work according to various RFC definitions (for example
RFC 2474, RFC 791). The user can also configure VLAN priority bits for
Level 2 Priority.

1.3 Functional Description

IPmux-1 supports a single E1 or T1 TDM interface; it provides TDM connectivity
across the IP network. A single bundle (group of timeslots) can be transmitted to a
predefined far-end bundle. IPmux-1 supports ICMP (ping), and generates ARP in
case of unknown next hop MAC addresses, answers ARP requests, and supports

802.3 Ethernet format.

IPmux-1E supports 4 BRI or 4 FXS ports for transparent connectivity over the IP
network.

Both IPmux-1 and IPmux-1E support Ethernet user port for user LAN connectivity.

Configuration and management are provided via the IPmux-1/1E local terminal,
Telnet or RADview management tool (SNMP).

Figure 1-9 shows a typical application for IPmux-1.

Unframed

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.

Use Fractional mode when grooming ISDN BRI channels from a remote IPmux-1E
unit.

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.

Note

Use Fractional with CAS mode when grooming FXS channels from a remote
IPmux-1E unit.

IPmux-1E ISDN BRI

The IPmux-1E ISDN BRI S interface operation modes 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 BRI card (see Chapter 2).

Note

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 in active mode all the
time.

If phantom feeding is enabled by the jumpers, the TE mode cannot be selected as
the IPmux-1E operation mode. If phantom feeding is disabled, both NT and TE are
valid options.

IPmux-1E FXS

IPmux-1E FXS operates in:

• E1 mode

• T1-D4 mode

• T1 ESF mode.

The IPmux-1E FXS 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.

BRI/FXS TS Assignment in a Bundle

BRI

The TS assignment in a Bundle for IPmux-1E with BRI (when working opposite
IPmux with E1/T1 or Megaplex) is assigned as follows:

Figure 1-11. TS Assignment in a Bundle for IPmux-1E/BRI

As shown in Figure 1-11, the 4 BRI channels consume 12 timeslots in the Bundle.
The E1/T1 IPmux should work in framed mode (no CAS).

The three TS groups in the bundle are assigned according to BRI channel numbers;
the first group is assigned to the lowest BRI channel that is enabled, etc.

FXS

The TS assignment in a Bundle for IPmux-1E with FXS is straightforward. Each
timeslot in a Bundle is assigned to a specific FXS channel. Time slots in the bundle
are assigned according to FXS channel numbers; the first timeslot is assigned to the
lowest FXS channel that is configured, etc. As shown in Figure 1-11, the 4 FXS
channels consume 4 timeslots in the Bundle.

The E1/T1 IPmux that works opposite the FXS channels should work in Framed
with CAS mode.

1-14 Functional Description

Diagnostic capabilities include E1/T1 or BRI S local and remote loopback tests for
rapid localization of faults. The E1/T1 or 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 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 E1, T1, ISDN or FXS
channels.

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 1-12,
Figure 1-14, and Figure 1-15).

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.

Note

Warning

• 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.

FXS/BRI

The available timing modes for the PCM clock are:

• Loopback Timing – available only when IPmux-1E BRI is configured as TE (not

available in BRI NT mode or for FXS 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.

Functional Description 1-15

• 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).

• 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 according to an external
network clock source, all the IPmux-1 units should be configured to work in
loopback timing mode (see Figure 1-12). 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 is equal to TDM bytes per frame (TDM bytes/frame
configuration).

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 E1/T1 level (see Figure 1-18).

To compensate for large PDV, configure the PDVT (jitter) buffer to a higher value.

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 E1/T1 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.

Note

To configure jitter buffer depth:

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 (see explanation of calculating intrinsic PDV, below).

Intrinsic PDV

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 =

48

eb

(n = 1 to 8).

For a bundle that contains a few timeslots (i.e. 1–3) the minimal jitter buffer should
be 6 ms.

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).

Ethernet Throughput

1-20 Functional Description

Configuring the TDM bytes per frame (TDM bytes/frame) parameter can reduce
Ethernet throughput (bandwidth or traffic travelling 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

IPmux-1/1E Installation and Operation Manual Chapter 1 Introduction

Ph:727-398-5252/Fax:[phone]

integer between 1 and 8. Configuring TDM bytes/frame to a higher value 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. Table 1-4 and Table 1-5 show throughput as a
function of the TDM bytes/frame configuration for full E1 and full T1.

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 internal switch port is used as the user
port, and the third is used as an Ethernet network port.

Internal Switch Operation Modes

Bridge Mode (no user rate limiter)

In this mode the internal switch performs transparent bridging, ALL internal ports
learn, update the internal tables, and make forwarding decisions according to the
source MAC only (not MAC + VLAN ID).

VLAN tagged frames are supported, however forwarding decisions are based on
MAC only.

Rate Limiter Mode

In this mode 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 5M and in 1 Mbps steps from 5M to 100M.

The internal switch (in the rate limiter mode) operates in the following way:

Functional Description 1-23

• The network port is in lock mode (no learning takes place). If this port must be

connected to a switch (not a hub), this is not a limitation, since all applications
involve connection to a backbone on an access switch.

• VLAN tagged frames are not supported (will be dropped)

• Access to the IPmux host for management is possible only from the network

port.

IPmux-1/1E Installation and Operation Manual Chapter 2 Installation

Order from: Cutter Networks

Ph:727-398-5252/Fax:[phone]

www.bestdatasource.com

IPmux-1E

The IPmux-1E FXS version needs NO user internal jumper configuration.

The IPmux-1E ISDN version contains jumpers for phantom feed (see Figure 2-1).
Open the case and check the positions of internal jumpers before the IPmux-1E
installation.

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 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.

Warning

Caution

Only qualified and authorized service personnel should have access to the
inside of the unit.

Disconnect the unit from the power line and from all the cables before
removing the cover.

Line voltages are present inside IPmux-1E when it is connected to power.
Moreover, under certain external fault conditions, dangerous voltages may
appear on the lines connected to IPmux-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-1E contains components sensitive to electrostatic discharge (ESD). To
prevent ESD damage, avoid touching the internal components, and before moving
jumpers, touch the IPmux-1E rear panel.

4.3 Diagnostic Tests

Maintenance capabilities include external and internal loopbacks.

External Loop

IPmux-1 can be set to an external loop to test the connection between the E1/T1
port and the PBX (refer to Chapter 3). In this mode, data coming from the PBX is
both looped back to the PBX and transmitted forward to the IP network (see
Figure 4-1).

This mode can also be achieved by a T1 FDL line loopback command.

Procedures

This appendix provides detailed instructions for setting up a test application using
IPmux-1 and IPmux-4. The application can be used as an optional test setup for an
IPmux unit, or can be used as a quick reference guide for basic configuration of an
IPmux unit.

5.1 Overview

Application

The section provides detailed instructions for configuring an IPmux-1 unit opposite
an IPmux-4 unit in a point-to-multipoint application including configuration via a
supervisory terminal (see Figure 5-1).

Guidelines

Certain guidelines/assumptions for configuring IPmux-1 working opposite
IPmux-4 that are relevant to this application are explained below.

IP Configuration

• The IP network can consist of either switches or routers. The minimum

requirement is 10M full duplex. Hubs or any half-duplex environments should
not be used.

• Each IPmux should be given an IP Address and a Default Gateway (if a routed

network is used).

E1/T1 Configuration

• TDM traffic will be sent between the central IPmux-4 and the two remote

IPmux-1 units at Station A and Station B over the IP network.

• The TDM traffic can either be generated by a BER tester connected to the

IPmux units or by a PABX. If a BER tester is connected to IPmux-4, a physical
loop can be inserted in the remote IPmux-1 E1 port to avoid using more BER
testers.

• The TDM equipment connected to the central IPmux-4 should be the clock

source for the whole application (i.e. it will operate in internal mode). The two
other TDM devices connected to IPmux-1 receive the clock from the Tx path
of the IPmux-1 units.

• Set the TDM device’s E1 parameters in accordance with the E1 parameters of

the IPmux units connected to them. For details, see Table 5-1and Table 5-2,
and the E1/T1 Configuration on the following pages.

• On the IPmux-4, only E1 port 2 will be used to connect to the remote

IPmux-1 units.

Creating Bundles and Connections

• After IP addresses and E1 parameters have been configured, create bundles on

each IPmux, followed by connections between the bundles.

• A bundle is a group of timeslots, encapsulated in UDP over IP over ETH

frames, which is sent over the IP network between the IPmux units. A bundle
can include between 1 and 31 timeslots for E1, and 1 to 24 for T1.
IPmux-1 can only be configured for 1 bundle. IPmux-4 can be configured to
have up to 31x4=124 bundles for E1 or 4x24=96 for T1. Each configured
bundle is given a Bundle Number that indicates to which E1 channel it
belongs, according to Table 5-1.

1 1-31 1–24

2 32-62 25–48

3 63–93 49–72

4 94–124 73–96

• A bundle containing 10 timeslots will be created on each IPmux-1 unit.

Two bundles, each containing 10 timeslots, will be created on IPmux-4.

• Bundle 1 on IPmux-1/Station A will be connected to Bundle 32 on IPmux-4.

Bundle 1 on IPmux-1/Station B will be connected to Bundle 33 on the central
IPmux-4.

Perform initial configuration of IPmux-1 and IPmux-4 via a standard ASCII terminal
connected to the IPmux-1 control port. However, after performing the initial
configuration (Host IP Address and Default Gateway), you can manage IPmux-1
and IPmux-4 using any of the following options:

Overview 5-3

• Use the terminal as a supervisory terminal, for performing all the management

activities supported by IPmux-1/4

• Manage IPmux-1/4 from any IP host using the Telnet protocol. After

establishing a Telnet session with IPmux-1, the Telnet protocol offers the same
functionality as the supervisory terminal, and in addition enables remote
access over IP networks.

Chapter 5 Application Configuration Procedures IPmux-1/1E Installation and Operation Manual

Order from: Cutter Networks

Ph:727-398-5252/Fax:[phone]

www.bestdatasource.com

• Manage IPmux-1/4 by means of SNMP-based network management stations,

e.g., the RADview network management station offered by RAD.

Changing Parameters

• Use the <Spacebar> on your keyboard to toggle between options in the

menus, and then save.

• Press <Enter> after entering a new parameter, such as the IP address, and

then save by pressing S.

• At any point and from any screen, you can press <Esc> repeatedly, backing

up until you reach the Main menu.

5.5 Checking the Application

Once you have finished configuring all the IPmux units, there are several levels on
which to check the application:

1. Use the IPmux Statistics

2. Check the TDM equipment statistics and functionality.

Using IPmux Statistics – Step 1

➤

To check the application using IPmux Statistics:

1. Select the Performance Monitoring menu in IPmux-4.

2. Select the Bundle Connection Status menu and verify that the connectivity
status is OK, and that you don’t have any sequence errors, underflows or
overflows rising. Verify this for both Bundle 32 and Bundle 33.

3. If the connectivity status is not OK (either local or remote failure):

 Check that all cables and physical connections on the IP side are OK.

 Check that the Bundle Connection configuration was properly made.

 Check that the IP Addresses and Default Gateways are configured correctly.

4. If you have sequence errors and underflows:

 Check under LAN Statistics that your Ethernet connection is full duplex. If

it is detected as half duplex, this could indicate that a problem exists in the
Auto-negotiation mechanism between IPmux and the switch/router. In this
case, set both devices to Auto-negotiation Disable, default type on IPmux
to full duplex, and either 10M or 100M, according to the switch/router
capability.

 Check under LAN Statistics that only the correct frames and correct octets

are received and transmitted. If other counters are rising, check the physical
connection of the IP side (cables, switch/router port, etc.).

Checking the Application 5-17

5. If you have underflows or overflows at set intervals of time:

 Check that all IPmux units are configured to the correct clock modes.

 Check that the TDM device is configured to the correct clock mode.

Chapter 5 Application Configuration Procedures IPmux-1/1E Installation and Operation Manual

Order from: Cutter Networks

Ph:727-398-5252/Fax:[phone]

www.bestdatasource.com

6. If you have underflows or overflows at non-set intervals of time:

 Try to gradually increase the jitter buffer size.

 Check that there are no E1alarms (such as LOS or LOF), through the IPmux

E1/T1 Statistics. If problems do exist on the E1/T1 level, check both physical
connections (cables and E1 ports) and E1/T1 parameter configuration
compatibility between the TDM equipment and the IPmux units (such as
CRC and CAS Enable/Disable).

 Check that the Bundle connection configuration was made correctly.

For further information, see the IPmux Troubleshooting and Diagnostics chapter.

Using TDM Equipment Statistics and Functionality – Step 2

After you have verified all the issues in Step 1, make the following checks.

1. Check that there are no alarms or BER on the TDM equipment.

2. If you are using a PABX check voice quality. IF echo exists, verify that you
haven’t configured the jitter buffer size to be too large (remember that the
initial configuration should be 3 ms, unless it is required to be larger due to
problems seen under the Bundle Connection Status).

Appendix A
Boot Sequence for

Downloading Software

A.1 General

This chapter provides a description of the IPmux-1/1E boot procedure via an ASCII
terminal for downloading software.

The IPmux-1/1E software is stored in flash memory in two sections, in the boot
sector and in the file system. The boot sector holds a boot program that calls up
the rest of the program from the file system.

The file system can hold two compressed copies of the IPmux-1/1E code. One
copy is called the operating file, and the other is called the backup file. The
operating file is the default-executable IPmux-1/1E code. The backup file is used
whenever the operating file is absent or corrupted.

A.2 Booting IPmux-1/1E

General

IPmux-1/1E boots up automatically. After powering up, no user intervention is
required, except when the user wants to access the file system to modify or update
the software or the IPmux-1/1E configuration.

Boot Sequence

The following is a description of the boot sequence. If the system is working
normally, the entire process is completed within 30 seconds. Refer to Figure A-1.

1. The boot program searches for the operating file in the file system.

− If the file exists, a message appears on the screen and the program

continues.

− If the file does not exist, the boot program searches for the backup file,

renames the file to Operating file (a message appears on the screen) and
continues.

− If there is no backup file, you must download a file via the out-of-band

interface (XMODEM protocol). The received file is saved as the operating
file in the file system.

2. Files in the file system are compressed and automatically decompressed into
the RAM memory before execution begins. A message appears on the screen.

3. After decompression, the IPmux-1/1E software starts to execute and the user
can begin working.

Accessing the File System

The file system menu is an option that allows the user to perform basic file transfer
operations. These operations are all optional.

If an operating file exists in the file system, there is a three-second delay.

Appendix B
Telnet

B.1 General

Telnet, which stands for Telecommunications Network, is a protocol that gives you
the ability to connect to a remote machine, by giving commands and instructions
interactively to that machine, thus creating an interactive connection. In such a
case, the local system becomes transparent to the user, simulating a direct
connection to the remote computer. The commands typed by the user are
transmitted directly to the remote machine and the response from the remote
machine is displayed on the user’s monitor screen. It is possible to manage the
IPmux-1/1E inband via remote ASCII Terminal using the Telnet IP protocol.

B.2 Using Telnet to Manage the IPmux-1/1E

Starting a Telnet Session

IPmux-1/1E is normally controlled by an ASCII terminal emulation application
running on an OS. To control IPmux-1/1E using Telnet, you must first open a
Telnet application on a local PC.

See Figure B-1 for an example of a Telnet logon dialog box. The Telnet application
present on the user’s computer may vary in appearance, but will have similar
fields.

To open a Telnet application:

➤

1. In the Host Name field, type the IP number of the IPmux-1/1E.

2. In the Port field, choose the Telnet option.

3. In the TermType field, choose the ANSI option.

4. Click Connect.

5. When prompted, type a valid username and password. The Telnet session is
now active.

Figure B-1. Telnet Logon Dialog

Telnet Operation

Telnet and ASCII terminal cannot be active at the same time.

If a terminal is active, a Telnet session cannot be established.

To establish a Telnet session:

➤

• Exit the terminal by selecting Exit in the Main menu.

If the auto-disconnect is ON, the terminal will be disconnected
automatically after 15–30 minutes if no characters were sent (see the ASCII
terminal Configuration Menu – Appendix E).

Terminal management has priority over Telnet, if a Telnet session is active
and a user logs on to the terminal, the Telnet session will be disconnected
and the terminal will be the active form of management.
Parameters set to default values via Telnet will not erase the Host and
Default Gateway parameters, to prevent a loss of connectivity.

Note

When configured to default values from the terminal, Host and Default Gateway
parameters will be optionally erased. The user can configure to default parameters
and then decide to keep/erase the Host and Default Gateway.

System Security

A user name and password is required to log on and initiate a Telnet session.

• The Terminal session exits to the password screen and the Telnet session

Appendix C
SNMP Management

Appendix C provides specific information for IPmux-1/1E management by SNMP
(Simple Network Management Protocol).

The SNMP management functions of IPmux-1/1E are provided by an internal
SNMP agent. The SNMP management communication uses UDP (User Datagram
Protocol), which is a connectionless-mode transport protocol, part of the IP
(Internet Protocol) protocol suite.

This appendix covers the information related to the SNMP environment.

C.1 SNMP Environment

SNMP Principles

The SNMP management protocol is an asynchronous command-response polling
protocol. All management traffic is initiated by the SNMP-based network­management station, which addresses the managed entities in its management
domain. Only the addressed managed entity answers the polling of the
management station (except for trap messages).

The managed entities include a function called an SNMP agent, which is
responsible for interpretation and handling of the management station requests to
the managed entity, and the generation of properly formatted responses to the
management station.

SNMP Operations

The SNMP protocol includes four types of operations:

• getRequest: Command for retrieving specific management information from
the managed entity. The managed entity responds with a getResponse
message.

• getNextRequest: Command for retrieving sequentially specific management
information from the managed entity. The managed entity responds with a
getResponse message.

SNMP Environment C-1

• setRequest: Command for manipulating specific management information
within the managed entity. The managed entity responds with a getResponse
message.

• trap: Management message carrying unsolicited information on extraordinary
events, which are events that occurred not in response to a management
operation reported by the managed entity.

Management Information Base (MIB)

The MIB includes a collection of managed objects. A managed object is defined as
a parameter that can be managed, such as a performance statistics value. The MIB
includes the definitions of relevant managed objects. Various MIBs can be defined
for various management purposes or types of equipment.

An object definition includes the range of values (also called instances) and the
following access rights:

• Read-only: Instances of that object can be read, but cannot be set.

• Read-write: Instances of that object can be read or set.

• Write-only: Instances of that object can be set, but cannot be read.

• Not accessible: Instances of that object cannot be read, or set.

MIB Structure

The MIB has an inverted tree-like structure, with each definition of a managed
object forming one leaf, located at the end of a branch of that tree.

Each leaf in the MIB is reached by a unique path. Thus, by numbering the
branching points starting with the top, each leaf can be uniquely defined by a
sequence of numbers.

The formal description of the managed objects and the MIB structure is provided
in a special standardized format, called ASN.1 (Abstract Syntax Notation 1). Since
the general collection of MIBs can also be organized in a similar structure, under
IAB (Internet Activities Board) supervision, any parameter included in a MIB that is
recognized by the IAB is uniquely defined.

To provide the flexibility necessary in a global structure, MIBs are classified in
various classes (branches). One is the experimental branch and another the group
of private (enterprise-specific) branch.

Under the private enterprise-specific branch of MIBs, each enterprise
(manufacturer) can be assigned a number, which is its enterprise number. The
assigned number designates the top of an enterprise-specific sub-tree of non­standard MIBs. Within this context, RAD has been assigned the enterprise number

164. Therefore, enterprise MIBs published by RAD can be found under

1.3.6.1.4.1.164.

MIBs of general interest are published by the IAB in the form of a Request for
Comment (RFC) document. In addition, MIBs are also often assigned informal
names that reflect their primary purpose. Enterprise-specific MIBs are published
and distributed by their originator, who is responsible for their contents.

MIBs Supported by the IPmux-1/1E SNMP Agent

C-2 SNMP Environment

The interpretation of the relevant MIBs is a function of the SNMP agent of each
managed entity. The general MIBs supported by the IPmux-1/1E SNMP agent are:

• rfc1213.mib (except the interfaces view which is supported via RFC 2233)

• ianaiftype.mib (defines the ifType)

• rfc1907.mib

• ces.mib

• rfc2127 (ISDN-MIB)

• rfc2495.mib (except Far End objects and RW configuration objects which are

different for each configuration) - replaces RFC 1406; which is now obsolete.

• rfc2494.mib

• rfc2239.mib

systems(1).radSysIPMux(3).IPmux1E(84)

Enterprise-specific MIBs supported by RAD equipment, including IPmux-1/1E6,
are available in ASN.1 format from the RAD Technical Support Department.

Management Domains under SNMP

In principle, SNMP allows each management station that recognizes the MIBs
supported by a device to perform all the management operations available on that
device. However, this is not desirable in actual practice, it is necessary to provide a
means to delimit management domains.

SNMP Communities

SNMP delimits management domains by defining communities. Each community
is identified by a name, which is an alphanumeric string of up to 255 characters
defined by the user.

The IPmux-1/1E SNMP agent defines strings of up to 10 characters (case sensitive,
numeric and alphabetical).

Any SNMP entity (both managed entities and management stations) is assigned a
community name by its user. In parallel, the user defines a list of the communities
for each SNMP entity that are authorized to communicate with the entity, and the
access rights associated with each community (this is the SNMP community name
table of the entity).

SNMP Environment C-3

Appendix C SNMP Management IPmux-1/1E Installation and Operation Manual

In general, SNMP agents support two types of access rights:

Read-Only: The SNMP agent accepts and processes only SNMP getRequest and
getNextRequest commands from management stations which have a Read-Only

community name.

Read-Write: The SNMP agent accepts and processes all the SNMP commands
received from a management station with a Read-Write community name.

Authentication

In accordance with SNMP protocol, the SNMP community of the originating entity
is sent in each message.

When an SNMP message is received by the addressed entity, it first checks the
originator's community. Messages with community names not included in the
SNMP community names table of the recipient are discarded. SNMP agents of
managed entities usually report this event by means of an authentication failure
trap.

The SNMP agents of managed entities evaluate messages originated by
communities appearing in the agent's SNMP community names table in
accordance with the access rights, as previously explained. Thus, a setRequest for
a MIB object with read-write access rights will nevertheless be rejected if it comes
from a management station whose community has read-only rights with respect to
that particular agent.

Network Management Stations

The IPmux-1/1E SNMP agent stores the IP address of the Network Management
Station (NMS) that is intended to manage it.

TFTP Download Procedures

D.1 Inband TFTP Download Procedure

New IPmux-1/1E software version can be downloaded to the IPmux-1/1E using
TFTP. There are three possible procedures:

• Users who access IPmux using Telnet can perform software download and
configuration upload/download using the configuration screens. For details,
see Download/Upload using TFTP (see Appendix E).

Warning

• Users who have access to the RADview Network Management – for more
details refer to RADview-HPOV Network Management System for IP

Applications.

• Users who access a MIB browser – the TFTP downloading procedure is
illustrated in Figure D-1.

Figure D-1. TFTP Downloading Procedure

The IPmux-1 manager station must be equipped with a TFTP server and the
new software.

The procedures in this chapter should be performed only by a UNIX expert.

To start download:

➤

1. Set the appropriate IPmux-1/1E MIB parameter. IPmux-1/1E then sends
requests to the TFTP server (where the new software resides) and receives
packets of data.

Inband TFTP Download Procedure D-1

2. If there is no TFTP server available to the main manager, assign a station where
there is a TFTP server installed. This server becomes a secondary manager. In
this case, the main manager only initiates the download process (by setting the
MIB parameter), which is then performed between IPmux-1/1E and the
TFTP server.

Preliminary Procedure

Before performing TFTP download:

➤

1. Ping IPmux-1/1E from the station running the TFTP server to ensure that
IPmux-1/1E has communication with the machine.

2. Log in as SUPERUSER (su).

3. Edit the file named inetd.conf found at the /etc directory, as follows:

− Search for the line starting with a # sign followed by tftp, for example, #

tftp and delete the # sign.

− At the end of that line, there is -S <directory name>.

In <directory name> specify only the path
downloaded to the IPmux-1; for example, /export/home/demo/tftp).

4. Save modified file inetd.conf and INIT the Unix machine; for example, in
Solaris type init 0 (not the same for SunOS or IRIX or HP-Unix).

5. After the Station reboots, type ovw & to open HPOV.
