• Do not use broken or unterminated fiber-optic cables/connectors or look

straight at the laser beam.

• The use of optical devices with the equipment will increase eye hazard.

• Use of controls, adjustments or performing procedures other than those

specified herein, may result in hazardous radiation exposure.

ATTENTION: The laser beam may be invisible!

Always observe standard safety precautions during installation, operation and maintenance of this
product. Only qualified and authorized service personnel should carry out adjustment, maintenance or
repairs to this product. No installation, adjustment, maintenance or repairs should be performed by
either the operator or the user.

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.

Ports Safety Status

V.11, V.28, V.35, V.36, RS-530,
X.21, 10 BaseT, 100 BaseT,
Unbalanced E1, E2, E3, STM, DS-2,
DS-3, S-Interface ISDN, Analog voice
E&M

xDSL (without feeding voltage),
Balanced E1, T1, Sub E1/T1

FXS (Foreign Exchange Subscriber) TNV-2 Telecommunication Network Voltage-2:

FXO (Foreign Exchange Office), xDSL
(with feeding voltage), U-Interface
ISDN

SELV Safety Extra Low Voltage:

Ports which do not present a safety hazard. Usually
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.

Australian Safety Requirements

WARNING: THIS EQUIPMENT MUST ONLY BE INSTALLED AND MAINTAINED BY SERVICE
PERSONNEL

In order to comply with Australian safety requirements for telecommunication equipment, observe the
following safety instructions:

1. VMUX-M/M-ETH-E1 module:
Remove JP7 and JP16 from the module circuit board.

2. VMUX-M/VC-E1/4 module:
Connection of this module’s ports to public telecommunication networks must be via a Line
Isolation Unit with a telecommunication compliance label.

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.

Chapter 1 Introduction

1.1 Overview

Vmux-2100 is a modular voice trunking gateway that enables up to 16 E1 or T1
circuits to be extended over a single E1, T1 or IP link. Vmux-2100 implements
G.723.1, G.729 A, G.711 compression and TDMoIP multiplexing algorithms to
send up to 480/384 voice channels over a single E1/T1 or IP link with transparent
CAS and CCS support. Vmux-2100 utilizes voice activity detection, silence
suppression, echo cancellation and other techniques to improve voice quality. The
gateway detects, generates and relays DTMF/MFR2/MFC signaling. In addition,
Vmux-2100 supports fax and data modem relay.

Versions

Note

Vmux-2100 can be managed locally via an ASCII terminal or remotely via Telnet
or RADview (RAD’s SNMP-based network management application).

Vmux-2100 includes voice and main link modules.

Voice Module

Voice module includes two or four balanced E1/T1 ports.

Main Link Module

A main link module supports the following interface combinations:

• Two E1 ports (balanced) with a UTP Ethernet port

• Two T1 ports (balanced) with a UTP Ethernet port

Vmux-2100 Installation and Operation Manual Chapter 1 Introduction

Features

E1 Main Link

Balanced redundant E1 main links ports use HDB3 coding and comply with
G.703, G.704, G.706, G.732 and G.823 standards. The E1 framers support
pass-through, G.732S and G.732N framing with or without CRC-4. Integral
LTU/DSU can be enabled for line protection and long haul options. Unbalanced
E1 connection is achieved via an external interface adapter.

T1 Main Link

Balanced redundant T1 main link ports use AMI coding, B8ZS zero suppression,
and comply with ANSI T1.403, AT&T TR-62411 and ITU-T G.703 standards. The
T1 framers support pass-through, SF, ESF. Integral DSU/CSU can be enabled for
line protection and long haul options.

Ethernet Main Link

Vmux-2100 has a half/full duplex, 10/100BaseT Ethernet port with autonegotiation
support. If autonegotiation is disabled, Vmux-2100 can be configured to any of the
following:

• 10BaseT – half or full duplex

• 100BaseT – half or full duplex.

The main link Ethernet port supports direct and indirect connection to the IP
networks.

Voice Modules

Vmux-2100 voice modules control E1/T1 frames, use G.723.1 (6.4 or 5.3 kbps),
G.729 A (8 kbps) and G.711 compression algorithms, and handle CAS/CCS
signaling transparently. Every group of two E1s or T1s is assigned a separate IP
address.

Voice Activity Detection mechanism allows optimizing bandwidth utilization, as
Vmux-2100 generates traffic only when voice activity is detected. Vmux-2100 uses
the G.723.1 A and G.729 B techniques for silence suppression and the G.168
standard for echo cancellation (up to 16 ms per channel). Vmux-2100 detects,
generates and relays DTMF/MFR2/MFC signals. In addition, Vmux-2100 supports
Group III fax relay (4.8, 9.6, 14.4 kbps) and transmits voice-band modem data.

Voice modules are hot-swappable.

TDMoIP Multiplexing

Vmux-2100 encapsulates the payload bytes in a UDP frame that is transferred over
IP and over Ethernet.

The number of TDM bytes in a multiplexed frame and packetizing interval are
user-configurable.

A destination IP address can be configured for each bundle (see Bundling, below).

Overview 1-3

Chapter 1 Introduction Vmux-2100 Installation and Operation Manual

Bundling

Bundle is a logical internal port of Vmux-2100, containing up to 60 timeslots. Each
E1/T1 group handles up to five bundles. A bundle is routed to a defined remote IP
address (remote group address). Each timeslot can be included in any bundle
belonging to its E1/T1 group. At the remote site, it can be connected to any
timeslot within a destination bundle.
Bundle QoS support:

• Labeling IP level priority (ToS).

• VLAN tagging and priority labeling according to IEEE 802.1 p&q.

The user can configure the ToS (Type of Service) of the outgoing IP packets. This
allows an en-route layer 3 router or switch, which supports ToS, to give higher
priority to Vmux-2100 traffic for delay-sensitive and secure applications.
Vmux-2100 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).

Timing

Available timing modes are:

• Loopback – The E1 or T1 transmit clock is derived from the E1/T1 receive
clock.

• Internal – Vmux-2100 features a separate internal oscillator for each voice
card. When a voice module is configured to operate in internal clock, transmit
(Tx) and receive (Rx) trunks use the clock supplied by its internal oscillator.

Diagnostics

Vmux-2100 supports local (internal) and remote (external) loopback activation on
E1/T1 links. The user can also perform tone injection towards the local PBX. In
addition, a ping utility is included to confirm IP connectivity to the remote units.

Statistics Collection

Vmux-2100 provides extensive statistics collection capabilities which include:
Ethernet (as per RFC 1643) and HDLC statistics, voice, signaling, bundles, CPU
and memory utilization.

Management

Vmux-2100 can be managed via a local terminal, Telnet or RADview, RAD’s
network management system. Vmux-2100 has a DB-9 female port for the direct
terminal connection. Alternatively, a supervisory terminal can be connected via a
modem link.

1-4 Overview

Software upload and download and configuration can be performed via the local
terminal, TFTP or via RADview. Remote units are managed via Telnet over an
inband management link running on an E1/T1 link.

Vmux-2100 Installation and Operation Manual Chapter 1 Introduction

Vmux-2100 supports a four-level security and user-authentication system:

• Administrator – Allowed to configure all the parameters of Vmux-2100.

• Operator – Allowed to perform all operations in the system except for user

administration (adding/deleting users, changing user definitions).

• Technician – Allowed to test Vmux-2100 and monitor its operation (for
example, monitoring alarms).

• Monitor – Allowed to monitor the Vmux-2100 operation.

When Vmux-2100 is managed over Telnet, up to five simultaneous management
sessions are allowed. Access to the Vmux-2100 software can be limited to the
ASCII terminal and RADview management by disabling the Telnet access.

Power

Vmux-2100 can be ordered with dual redundant hot-swappable power supplies,
supporting load sharing.

• AC: 100 to 240 VAC

• DC: 30 to 70 VDC (48 VDC, nominal).

Voice Modules

Voice modules include two or four E1/T1 ports which receive E1/T1 trunks from
PBXs. Every two E1 and T1 ports are referred to as a group, which receives a
separate IP address.

Signaling

Signaling information is processed according to signaling mode: CAS for E1,
Robbed Bit MF for T1, or CCS for E1 and T1.

• CAS/Robbed Bit MF – The signaling data is processed by a separate DSP by
extracting the ABCD bits and reporting any change in their status to the host.
The reporting format is similar to E1, T1 ESF and T1 SF. In addition, the
signaling DSP employs a refresh mechanism to update the host with the most
recent status of the ABCD bits. The ABCD bits can be manipulated by using
translation rules, which are defined by means of signaling profiles.

A profile enables the user to select the translation of each individual signal bit.
The available selections are A, B, C, D (value copied from the corresponding
incoming bit), NOT A, NOT B, NOT C, NOT D (inverted value of
corresponding incoming bit), 0 (always 0), and 1 (always 1).

1-6 Functional Description

Vmux-2100 Installation and Operation Manual Chapter 1 Introduction

In addition to the translation of individual bits, the signaling profiles can also
be used to define the signaling bit patterns that indicate the idle and OOS
states.

• CCS – The signaling information is transferred transparently to the host, which
encapsulates the HDLC frame with the proper IP header and sends it to the
main link. The following protocols are supported: ISDN, QSIG and SS7. HDLC
data can be extracted from any set of timeslots and sent to a single destination.
When operating with SS7 signaling, it is possible to control amount of the
keep-alive bits transferred over the signaling links.

Compression

The DSPs handle the voice traffic by compressing it according to G.723.1 (6.4 or

5.3 kbps) and G.729 A (8 kbps), or digitizes it according to the G.711 requirements

(A-law and µ-law). Compression methods are user-selectable per bundle.

Voice Activity Detection

Voice Activity Detection (VAD) uses digital signal processing techniques to
distinguish between silence and speech on a voice connection. VAD reduces the
bandwidth requirements of a voice connection by generating traffic only during
periods of active voice conversation. With Comfort Noise Generation supported at
the remote site, VAD significantly reduces bandwidth consumption without
degrading voice quality. VAD achieves additional bandwidth savings when
combined with voice compression techniques.

TDMoIP Multiplexing

Compressed voice payload is multiplexed by using the TDMoIP technique. The
multiplexing is performed by the Vmux-2100 software. The DSPs send a
continuous stream of voice packets; which are put together into a TDMoIP frame
by adding AAL2 headers and a TDMoIP header. Figure 1-6 illustrates the TDMoIP
frame structure.

VLAN Support

Vmux-2100 supports VLAN, according to IEEE 802.1p&q. When VLAN support is
enabled Vmux-2100 adds four bytes to the MAC layer of the Ethernet frame. The
content of these bytes, MAC layer priority and VLAN ID, can be set by the user. In
this mode, only VLAN format frames are sent and received by Vmux-2100. The
following figure describes the VLAN tag format.

Ethernet Main Link

10/100BaseT main link receives Ethernet frames from the voice modules via the
Ethernet switch and forwards them to the remote device over the IP network. The
10/100BaseT main link of Vmux-2100 supports full duplex transmission with
autonegotiation and half duplex with the backpressure option.

E1/T1 Main Link

When using E1/T1 main link, Vmux-2100 adds HDLC flags to the Ethernet frames
and transmits them over a TDM network. The E1/T1 main link interface of
Vmux-2100 is fully redundant. When both of links are configured as active,
Vmux-2100 starts sending data over the one that was connected first. If a loss of
synchronization is detected on an active link, Vmux-2100 automatically switches
to the backup link.

The E1/T1 links operate with loopback timing by deriving clock from the device
connected to its E1/T1 port or with internal clock provided by the Vmux-2100
internal oscillator.

Functional Description 1-9

Chapter 1 Introduction Vmux-2100 Installation and Operation Manual

Bandwidth Utilization

By using TDMoIP multiplexing and the voice activity detection, Vmux-2100
supports a higher number of voice channels over TDM than it is possible by
utilizing conventional compression methods alone. TDMoIP multiplexing and
grouping the timeslots of compressed voice together into bundles with a common
IP address reduces the actual bandwidth used per channel to as low as 4 kbps
(16:1), when all channels are active. Better compression, up to 20:1, is achieved
when some of the voice channels are idle.

The actual bandwidth utilization is determined by the following factors:

• Header sizes:

 Ethernet – 18 bytes
 IP – 20 bytes
 UDP – 8 bytes
 TDMoIP – 4 bytes
 VLAN (if exists) – 4 bytes.

• Size of the voice packet:

 G.723 – 24 bytes + AAL2 header (3 bytes) + voice payload (4 bytes)
 G.729 – 10 bytes + AAL2 header (3 bytes) + voice payload (4 bytes).

• Packet interval:

 G.723.1 – 30 msec
 G.729 – 10 msec.

• Number of timeslots in a bundle

• Silence percentage. Studies show that an average person speaks only 40% of

the time during a telephone conversation. 50% of the time is spent listening to
the other party, while the remaining 10% is spent quietly contemplating.

• Connectivity packets – 64 bytes per minute.

Calculating Approximate Bandwidth Utilization

Let us calculate an approximate bandwidth for 30 timeslots in one bundle with
G.723.1 (6.4 kbps) compression, 60 % of silence:

[(50 × 1000/40) + (30 × 31 × 1000/30 × 0.4)] × 8
1000

where:

• 50 – size of Ethernet, IP, UDP, TDMoIP headers

• 1000/40 – packets per second (pps) transmission rate, calculated according to

the packetizing interval chosen (40 msec in this example)

• 30 – number of timeslots

• 31 – size of the compressed G.732 packet plus AAL2 header and voice payload

+ 0.00853 = 109.208 kbps

• 0.4 – 60% of silence

• 8 – conversion from bytes to bits

• 1000 in the denominator – conversion from bits to kilobits

• 0.00853 – connectivity packets rate (64 bytes per minute) converted to kbps.

Management from a

Terminal

The configuration of Vmux-2100 is performed via menu-driven embedded
software, using a standard ASCII terminal or a PC running a terminal emulation
application connected to the rear panel CONTROL port. Alternatively, you can
configure Vmux-2100 via Telnet connection, which also establishes an inband
management link to the remote unit.

4.1 Preparing for the Control Session

This section describes how to prepare Vmux-2100 and the supervisory terminal for
the control session.

Control Port Interface Characteristics

Vmux-2100 includes a V.24/RS-232 asynchronous DCE port, designated
CONTROL and terminated in a 9-pin D-type female connector. The control port
continuously monitors the incoming data stream and immediately responds to any
input string received through this port.

The terminal can be connected either directly to the Vmux-2100 control port, or
through a modem or any other type of full-duplex data link.

• Direct connection to terminals. Since terminals usually have DTE interfaces,
the connection to the port is made by means of a straight cable.

• Connection through a modem or data link. In this case, you need a cross cable
(RAD’s CBL-VMUX-MM-MODEM) to connect to the CONTROL connector
(see Appendix A for the cross cable wiring diagram).

Preparing the Terminal

Any standard ASCII terminal (a “dumb” terminal or a personal computer running
a terminal emulation application) equipped with a V.24/RS-232 communication
interface can be used to configure Vmux-2100. Appendix A details the pin
assignment and control signal directions of the Vmux-2100 control connector.

Data Terminal Ready (DTR)

When connected and turned on, the terminal sets the DTR line ON (active) to gain
control over Vmux-2100 and starts a configuration or monitoring session.

Preparing for the Control Session 4-1

Chapter 4 Management from a Terminal Vmux-2100 Installation and Operation Manual

Initiating a Control Session

Vmux-2100 supports two default terminal rates:

• 115.2 kbps, for 20–30 seconds after the power-up, until the boot sequence is
completed. Supervisory terminal connection may be required at this stage for
software downloading purpose.

• 9.6 kbps, during normal operation.



To initiate a control session:

1. Connect the terminal cable to the CONTROL connector of Vmux-2100.

2. Turn the control terminal on.

3. Configure the terminal to the default communication parameters: 9.6 kbps,
one start bit, eight data bits, no parity, one stop bit, no flow control, VT100
emulation.

You are now ready to start a control session.

Levels of Security

Vmux-2100 supports a four-level security and user authentication system:

• Administrator – Allowed to configure all the parameters of Vmux-2100.

• Operator – Allowed to perform all operations in the system, except for user

administration (adding/deleting users, changing user definitions).

• Technician – Allowed to test Vmux-2100 and monitor its operation (for
example, monitoring alarms).

• Monitor – Allowed to monitor the Vmux-2100 operation.

The maximum number of the users supported by Vmux-2100 is 20. When
managing Vmux-2100 over Telnet, up to five simultaneous management are
permitted. Only one administrator is allowed to enter the management session at a
time.

Vmux-2100 displays the management menus in accordance with a user’s access
rights. For example, configuration screens dealing with the unit configurations are
not available for the users, who logged in as technicians or monitors.

Default Security Configuration

Vmux-2100 is supplied with one administrator account:

• User name: admin

• Password: 12345.

When the first management session is initiated, it is recommended to create a new
administrator account, and delete the default one.

Note

If the password is lost, consult your local RAD distributor.

3. From the Dial-In Modem menu, choose:

 Disable to disable connection of a dial-in modem to the control port

 Enable to enable connection of a dial-in modem to the control port.

Note

If an ASCII terminal or PC is connected directly to the control port while the dial-in
modem access option is enabled, signals from the terminal or PC may be confused
with modem control signals by the Vmux-2100 modem auto detect capability and
inadvertently cause the Vmux-2100 to disable the terminal or PC connection. To
avoid this situation, verify that the Control port dial-in modem access is set to
Disable (this is the default setting) before attempting to make a direct terminal or
PC connection to the Control Port (this can be accomplished safely via Telnet). If
dial-in modem access is not required, it is recommended to leave this option
disabled.

Configuring Signaling Information

Vmux-2100 allows you to configure the signaling parameters according to the
selected signaling mode: CAS for E1, Robbed Bit MF for T1 or CCS for E1/T1.
Signaling mode is selected via the E1 Parameters menu of the voice card (see the

Configuring External E1/T1 Ports section below).

Note



• CAS/Robbed Bit MF – You must configure a signaling profile and signaling
table associated with it (ABCD bits, idle code and OOS signals).

• CCS – When working with CCS-SS7, you can configure the fill-in packets flow
by selecting the SS7 keep-alive suppression rate.

Configuring Signaling Profiles

If you are using CAS signaling, you must configure the signaling system of
Vmux-2100 to make it compatible with the signaling method used by the PBXs
connected to the voice E1/T1 ports. The management software allows you to
manipulate the ABCD signaling bits and methods of representation of the idle
code and out-of-service signals generated by the PBXs (see Table 4-1). Signaling
conversion is used for connection of PBXs, which use different signaling formats.

You can store up to five signaling profiles; Vmux-2100 uses only one of them at a
time. The signaling profile selection is performed via the E1 Parameters menu of
the voice card (see the Configuring External E1/T1 Ports section below).

The signaling profile configuration is available only for the units operating with CAS
signaling.

To configure the signaling profile:

1. From the Management menu (see Figure 4-6), choose Signaling Configuration

The Signaling Configuration menu appears (see Figure 4-15).

IDLE SIGNAL Selects the code transmitted

on A, B, C, and D bit when the
channel is idle

OOS SIGNAL Selects the code transmitted

on A, B, C, and D bit when the
channel is out of service

Configuring Keep-Alive Suppression Rate

When Vmux-2100 with CCS signaling is connected to the PBXs operating with the
SS7 signaling, the PBXs use one timeslot to transmit signaling information. The
signaling information is passed over the signaling link in the form of the following
signal units:

0 – Transmits zero

1 – Transmits one

A – Transmits the incoming A bit

B – Transmits the incoming B bit

C – Transmits the incoming C bit

D – Transmits the incoming D bit

NOT A – Inverts the incoming A bit and transmits it

NOT B – Inverts the incoming B bit and transmits it

NOT C – Inverts the incoming C bit and transmits it

NOT D – Inverts the incoming D bit and transmits it

0 – Transmits zero

1 – Transmits one

0 – Transmits zero

1 – Transmits one

• Message signal units (MSUs) provide all signaling associated with call setup
and tear down, database query and response, and SS7 network management.

• Link status signal units (LSSUs) provide information on the link status
between the network nodes (initiation of link alignment, quality of the
signaling traffic etc).

• Fill-in signal units (FISUs) carry no information payload. They occupy the link,
when there are no MSUs or LSSUs to send. FISUs are also referred to as
“keep-alive” messages.

Often, in the absence of signaling traffic, the signaling links become flooded with
the FISUs, causing communication disruptions. In order to prevent this, you can
enforce Vmux-2100 to drop certain amount of FISUs (up to 90%). You can also
disable the FISU dropping by configuring the keep-alive suppression rate to 0%. It
is necessary, when working with non-SS7 CCS signaling (for example ISDN), or if
the FISUs are used to acknowledge the receipt of the signaling messages. In the
latter case, system performance may become unsatisfactory.

 Set the Ethernet parameters of the main link 10/100BaseT port, if necessary

(autonegotiation or LAN mode).

 Configure the E1/T1 parameters of the main link, if necessary (framing

mode, restoration time, clock source, interface type, idle code).

 Assign the E1/T1 main link timeslots to carry user data.

2. Configure external E1/T1 at a group (two E1/T1 ports of the same module)
level:

 Assign IP address to a group.

 Add bundles to a group (up to five bundles per group)

 Configure each bundle (frame size, destination IP, destination bundle,

packetizing interval, TOS parameters, compression method, fax relay,
VLAN parameters).

3. Configure external E1/T1 at a single E1/T1 level:

 Configure each E1/T1 port at the physical level (framing mode, restoration

Figure 4-34. Connectivity Parameters Menu

Vmux-2100 constantly monitors status of all connected bundles by sending
the 64-byte keep-alive messages to remote device. Connectivity is
confirmed by receiving a reply from the remote unit. This process is similar
to pinging remote IP hosts. If reply is not received, usually due to the main
link failure, Vmux-2100 disconnects the bundle and generates the BUNDLE
IS OOS alarm. When the BUNDLE IS OOS alarm is generated, Vmux-2100
notifies appropriate PBX by sending “all 1s” string (CCS signaling) or OOS
message (CAS signaling) on all timeslots of the disconnected bundle. This
notification allows the attached PBX to stop transmitting over a faulty E1
and switch to a backup link.

You can specify the following connectivity parameters:

Connectivity packet rate (frequency of sending the keep-alive packets,



from one packet per 1 second to one packet per 60 seconds)

Connectivity timeout cycles (number of attempts within which



Vmux-2100 expects to receive at least one reply from the remote
device).

For example, if you set the connectivity packet rate to 60 seconds and
connectivity timeout to 3, Vmux-2100 disconnects a bundle from which it
did not receive at least one reply within 180 seconds.

Chapter 4 Management from a Terminal Vmux-2100 Installation and Operation Manual

Note

When operating Vmux-2100 in a TDM network (for example, leased line), where
delays are minimal, you can configure Vmux-2100 to generate the keep-alive
packets more frequently to ensure the early notification of a main link failure. In IP
networks, where delays are more common, it is recommended to set the
connectivity parameters to their maximum values.

Vmux-2100 Installation and Operation Manual Chapter 4 Management from a Terminal

Note

If you intend to change the voice parameters, it is recommended to disconnect a
bundle before configuring it. The bundle must be disconnected at the local and
remote sites. If you do not disconnect the bundle, you must perform reset of the
local and remote voice modules carrying the E1/T1 links which timeslots belong to
the bundle. The voice modules must be reset after you complete configuring the
voice parameters.

Configuring External E1/T1 Ports

Configuration of the external E1/T1 ports located on the Vmux-2100 voice
modules (V-2E1, V-4E1, V-2T1, V-4T1) is similar to the configuration of the E1/T1
ports of the main link modules (M-IPE1, M-IPT1). In addition to the standard
configuration procedures listed in the Configuring the E1 Main Link Port and

Configuring the T1 Main Link Port sections above, you must perform the following:

Note

• For T1 links, select a signaling mode:

 Robbed Bit MF

 CCS.

• For E1 links, selecting the frame mode automatically determines the signaling
mode:

 G.732S or G.732S-CRC4 framing: CAS signaling

 G.732N or G.732N-CRC4 framing: CCS signaling.

If you intend to change E1/T1 signaling, it is recommended to disconnect a bundle,
to which the E1/T1 timeslots are assigned before configuring the signaling mode.
The bundle must be disconnected at the local and remote sites. If you do not
disconnect the bundle, you must perform reset of the local and remote voice
modules carrying the E1/T1 links after you complete configuring the E1/T1 signaling.

• When operating with CAS (for E1 links in G.732S frame modes) or RBMF (for
T1 links) signaling, it is necessary to assign a signaling profile to the E1/T1 link.
In such cases the Profile[1 - 5] option will appear. The profile must be
compatible with the PBX signaling (signaling profile configuration is explained
in the Configuring Signaling Information section above).

• Configure the E1/T1 timeslots, as explained below.

Configuration of the E1/T1 ports located on the voice modules is performed via the
External 1 and External 2 menus (Configuration > Card >Slot 1/Slot 2/Slot3/

Slot 4 > Group 1/Group2 > External 1/External 2 > E1 Parameters/T1

5.2 Outline of Configuration Procedure

The recommended configuration procedure of the local and remote Vmux-2100
units include the following steps:

• Configuring of the IP host parameters for both units via an ASCII terminal
connection.

• Installing the two units at their locations.

• Configuring the local Vmux-2100.

• Saving the configuration file (cnfg.dat) of the local unit at the management

station.

• Downloading the configuration file to the remote Vmux-2100 and updating its
database.

• Changing the IP addresses of the remote E1/T1 groups to the valid ones.

5.3 Configuring Vmux-2100 for Operation with CAS

Signaling

Most of the configuration procedures are performed on the local unit, except for
the defining IP host parameters, and IP addresses of the remote E1/T1 groups.

Configuration procedure is divides into three main stages:

• Defining system parameters.

• Configuring main link parameters.

• Setting voice card parameters.

Note

You must save the selected values by updating the Vmux-2100 database. If the
database is not updated, Vmux-2100 discards all the user settings when it is reset.
You can save selected values at any stage of the configuration procedure.

Configuring System Parameters



To configure the Vmux-2100 system parameters:

1. Configure an ASCII terminal to: 9.6 kbps, one start bit, eight data bits, no
parity, one stop bit, no flow control, VT100 emulation

2. Connect the terminal to the local Vmux-2100 DB-9 CONTROL port.

3. Initiate the control session by entering the user name and password.

4. Verify that the main link card (M-IPE1) and the voice card (V-4E1) are
identified by Vmux-2100 (Main Menu > Inventory).

5. Display the Host IP menu and enter the host IP address (172.17.15.10), its
subnet mask and default gateway values (Main Menu > Configuration >
System > Management > Host IP).

6. Repeat step 2 to step 5 for the Vmux-2100 unit to be installed at the remote
location.

Note

Chapter 6 Diagnostics

This chapter describes the Vmux-2100 diagnostic functions, which include:

• Tone injection

• Loopbacks (local and remote)

• Ping utility.

6.1 Tone Injection

The test tone is a data sequence at a rate of 1 kHz. This data sequence is identical
to the data sequence that would have been generated if a 1 kHz signal having a
nominal level 0 dBm were applied to the input of the channel speech processor.
The tone should be received clearly by the corresponding subscriber connected to
the PBX at the nominal receive level. Vmux-2100 supports tone injection towards
the local side only (see Figure 6-1).

Note



The tone injection is activated individually per timeslot. However, multiple tone
injections can be run at the same time. Vmux-2100 allows you to set the tone
injection timeout causing the tone relay to deactivate automatically after the
desired period of time.

Monitoring and Statistics

Collection

This chapter describes the alarms, sanity checks (configuration errors and
warnings), main link and voice module statistics supported by Vmux-2100.

7.1 Alarms

Vmux-2100 detects fault conditions and initiates alarms and events to alert the
user:

• Alarms (major and minor) have two statuses, ON and OFF. Alarm status
changes to OFF, when a fault condition that caused it is cleared.

• Events have only ON status.

Alarm Buffer

Vmux-2100 maintains two alarm buffers:

• Temporary buffer, represented in the Display All Alarms screen. The user can
delete all alarms, including the active ones from this display.

• Permanent buffer, represented in the Alarm Status screen. The user can
delete only inactive alarms from the Alarm Status display.

An alarm enters simultaneously both Display All Alarms and Alarm Status logs, and
the ALM LED turns on to indicate the condition. In addition, Vmux-2100 displays
ALARM ON indication in the top right-hand corner of the terminal screen. When
the event that caused the alarm is cleared, the alarm status changes to OFF,
enabling the user to remove it from the permanent buffer.

Working with the Temporary Alarm Buffer

The temporary buffer is represented by the Display All Alarms screen.



To access the Display All Alarms screen:

1. From the Main menu, choose Monitoring.

7.2 Sanity Checks

Configuration errors and mismatches are rendered by the Vmux-2100
management software as sanity checks. Their main purpose is to maintain the
database validity. Vmux-2100 supports two types of the sanity check messages:

• Error – major configuration error which prevents the Vmux-2100 database
from updating and saving changes.

• Warning – minor configuration error which allows the user to update the
database and save the changes.

Displaying the Sanity Errors and Warnings

Each time you update the Vmux-2100 database, the management software
analyses the changes. If a major error is detected, Vmux-2100 aborts the database
update and displays the following message:

Data base wasn’t changed. Sanity Error - Check alarm.

If a minor error is detected, Vmux-2100 updates the database and displays the
following message:

Sanity Warning - Check alarm.



To display the sanity errors and warnings:
