CHAPTER 1 INTRODUCING THE V100
V100 Versatile Multiplexer Technical Manual Version 2.2
Page 8 of 231
1Introducing the V100
1.1 General Overview
The V100 multiplexer represents the culmination of many years’ experience in the design of
communications equipment. Not only does it provide an impressive range of features and options, but
uses innovative and state-of-the-art technology to yield a high-performance solution to a diverse range of
voice/data/audio and IP applications.
The architecture of the product has been designed to meet all essential requirements and yet allow for
almost unlimited expansion and flexibility. The 1U chassis is the most compact format for mobile comms
and its rugged and reliable design makes the V100 ideal for military or commercial deployment in remote
areas. By linking many chassis together, a sophisticated hub site can be commissioned which exploits the
versatile routing and bandwidth agility of the product.
The V100 allows voice, data, audio and IP sources (termed as “tributaries”) to be multiplexed together
over common network paths (termed as “aggregates”) between V100s.
All data ports are viewed as universal, as they may be configured to be either aggregate link or tributary
port. They may be synchronous or asynchronous, presented on a standard 15-way connector with V.24,
V.11, RS530, V.35 or RS449 electrical interfaces all selectable from the supervisor port without the need
to change cards or remove the lid. Each data port provides the ultimate flexibility in clocking options. This
allows a unit to accept, source or onward link clocks, or even operate with asymmetric bandwidths. The
basic unit is fitted with two data ports.

CHAPTER 1 INTRODUCING THE V100
V100 Versatile Multiplexer Technical Manual Version 2.2
Page 9 of 231
Two option card bays (one in the Compact Multiplexer) offer a wide range of hardware configurations to
suit the application. The cards are easy to install from the rear panel and provide analogue voice/fax
channels, additional data ports, ISDN BRI extension, high quality audio compression and E1/T1
compressed voice facilities. In addition to this, a Special Option Card bay allows the user to install an ISDN
basic rate terminal adapter, an E1 link card or a TDM interface card and finally, a 10/100base-T port on
the front panel (RevD units) provides connectivity for a Local Area Network (LAN) and integrates an IP
routing and/or bridging function inside the mux.
The product offers point-to-multipoint link connectivity. This allows star or mesh network topologies to be
designed with fully dynamic call routing and no need to decompress at the hub. Any or all data ports
(including ISDN option card, E1 option card and TDM option card) may be used as aggregates, since the
internal architecture will treat all ports in the same way. The flexibility of network topology means that
remote sites with few channels may interoperate with complex central sites with complete compatibility.
The LAN port may also be used to provide aggregate links across IP networks.
Despite the high level of integration, many networks will require more channels than can be supported in
a single 1U chassis. This may readily be achieved using the High-Speed Channel (HSC), a 4Mbps serial
bus for concatenating units together. If more than two units are required to be connected at the hub, this
can be achieved by using back-to-back cables or by configuring IP Aggregates. This bus may be used to
route traffic between any two units in the stack, thereby expanding the number of available channels.
Chassis linked together in this way may thus operate as one cohesive unit and subject to bandwidth
restriction, aggregates or tributaries may be assigned wherever they are required. This feature allows the
network manager to solve complex topologies using the V100 chassis as redeployable building blocks.
The constraints of complex networks often lead to bandwidth restrictions or bottlenecks during periods of
congestion. For this reason, it is possible to set a primary and a secondary route for all calls to take
through the network. In addition to this, up to six user configurations may be designed and stored, which
may be invoked as alternative strategies in the event of link failure or disruption. The network manager
has access to comprehensive statistics and alarms which may stimulate such a disaster recovery plan.
A V100 network may be managed from the dedicated supervisor port of any chassis in the network. The
user logs on to the required unit and configures the network from the most convenient management port
using a clear and simple display, which may be accessed using a PC running a terminal emulation package
such as HyperTerminal under WindowsTM. Alternatively, the supervisor may be operated in a terse
teletype mode for integration into a central network management system. In either case, the port uses an
RS232 interface. The supervisor may also be accessed using the telnet protocol in an IP network.
This user manual describes the use, configuration and installation of the V100 multiplexer.

1.2 Capabilities
1.2.1 Analogue Voice/FAX
A wide range of ITU-standard algorithms may be individually selected according to
bandwidth and quality requirements, with bit rates from 5.3Kbps up to 64Kbps. All
channels support Group 3 FAX at 2400-14400bps, V.22, V.22bis and V.32bis modem
relay and provide G.168 echo cancellation. Bandwidth may be permanently assigned or
used on-demand to optimise link use, when it may be redistributed among data
channels using the Dynamic Bandwidth Allocation feature. Comfort Tone Generation and input/output gain
adjustment allow the voice channels to be optimised for all situations.
The analogue voice cards are available in 2-, 4- or 8-channel form and provide FXO, FXS and 4-wire E&M
(Tie-line) interfaces for connection to private analogue circuits. DTMF, MF and E&M signalling standards
are supported.
1.2.2 Secure Voice Relay
With the addition of the optional Secure Voice Relay card, the analogue voice/FAX
card is able to support data relays for STU-IIb and STU-III secure telephone units.
This demodulates the encrypted traffic and passes it as data to the remote unit,
where it is remodulated for the secure telephone at that end. The key benefit is that
the encrypted traffic can then pass through a low-speed compressed voice channel, thereby saving
valuable bandwidth. At no time is the sensitive traffic decrypted.
1.2.3 Data
The V100 chassis has two dedicated data ports in the chassis and further ports are
available by adding 4-channel option cards, to yield a maximum of ten channels per
chassis. Any port may be synchronous or asynchronous, at speeds up to 2Mbps and
may be used as an aggregate or a tributary. It is possible to assign any tributary
channel to be multiplexed over any aggregate channel, or to pass via the HSC to a port
on any other unit, subject to bandwidth restrictions.
Ports configured as aggregates may be operated in fixed-carrier mode (for example over VSAT SCPC
links) or in switched-carrier mode (for example in DAMA, Inmarsat-B or SCADA networks).
Data ports are implemented on 15-way ‘D’-type connectors and support a wide range of software–
selectable interface standards. Each port has two independent Phase-locked Loops (PLLs), which permit
the RX and/or TX clock to be locked to any other port in the system, thus permitting onward-linking and
asymmetric bandwidth operation if required.

CHAPTER 1 INTRODUCING THE V100
V100 Versatile Multiplexer Technical Manual Version 2.2
Page 11 of 231
1.2.4 ISDN BRI Extender
The ISDN BRI Extender card is able to present a Basic Rate interface (2B+D) at a
remote site, by converting a standard terrestrial ISDN service into a synchronous
internal connection and then back again at the far end. In this way, ISDN services
may be simultaneously combined with any other services that the V100 can offer.
Since the card operates at the physical level only, it remains independent of layers 2 and 3 of the ISDN
network protocol and so can be used world-wide without restriction.
The card may be used in switched or permanent modes, allowing the user to take full advantage of the
flexible bandwidth control of the V100.
1.2.5 High Quality Audio
Broadcast-quality audio is supported by the MPEG option card, which is a
complete MPEG/G.722/G.711 stereo audio Codec with a full range of MPEG1 and
MPEG2 sampling and compression rates. The card presents left and right
analogue channel interfaces on XLR connectors and also supports digital stereo
AES/EBU operation with connection via the left channel. The local
encoder/decoder algorithms may be different, with decoders automatically synchronising to the received
coding, sample rate and bit rate.
The V100 system is designed to operate on asymmetric links through its versatile clocking architecture. It
is therefore not only possible to select different coder/decoder types but to operate in simplex mode if
required.
1.2.6 ISDN Basic Rate Interface Link Card
An optional integral ISDN Terminal Adaptor (TA) may be fitted which provides access
to the ISDN2 service for backup or bandwidth-on-demand. This card is available with
either an ‘S0/T0’-bus interface or a ‘U0’-bus interface and is fitted in the Special
Options slot. International ISDN protocol variants are supported from the factory
upon request.
The ISDN TA is configured from its own menu page and routing page, which allows the user to enter a
primary and secondary ISDN number, set up call control parameters and select clock sources for locking
the rest of the system.
The ISDN TA offers connectivity with both land and sea based Inmarsat GAN services.
1.2.7 E1 Link Card
An optional E1 link card may be fitted to provide an aggregate service over an E1 interface.

CHAPTER 1 INTRODUCING THE V100
V100 Versatile Multiplexer Technical Manual Version 2.2
Page 12 of 231
1.2.8 TDM Link Card
A TDM Link card may be fitted in the Special Option slot to provide an additional aggregate interface port.
This port allows tributary data channels to be selected as Time-Division Multiplexed (TDM) ports, which
are then carried over the new aggregate, not in a packetised manner but over fixed timeslots. The benefit
of this feature is that such data does not then suffer the error-extension phenomenon associated with all
packetised protocols, where a single bit error affecting a packet causes the whole packet to be rejected.
When a TDM Link card is fitted, the network must provide the master clock and the bit rate is restricted to
512Kbps
1.2.9 Expansion – The High Speed Channel
The V100 has a unique High-Speed serial Channel (HSC) dedicated to the interconnection of units. This
port allows data and control information to pass between two chassis, so as to form a concatenated unit.
Such a combination can then operate as one cohesive unit, a feature which not only gives expansion
capability but also allows units to be decommissioned and replaced without disruption.
A 9-way D-type connector presents the 4-wire RS485 serial bus, which runs a proprietary protocol at
4Mbps. This allows up to 2Mbps of full-duplex data to pass between linked units and also carries receive
and transmit clock signals to all units. In this way, any data port on either unit may be used as an
aggregate WAN port and the demultiplexed data routed to a tributary channel on either chassis via the
HSC. Full flexibility of clock sourcing via the HSC permits the network clock to be onward-linked to any
other unit.
1.2.10 10/100base-T Integrated Router
Revision D of the V100 chassis introduces the integrated IP Router, presented on an RJ45 connector on
the front panel. The majority of applications now demand IP connectivity in the field, as well as the
established voice and data facilities. The V100 presents an integrated 10/100base-T port capable of
supporting IPV4 bridging and routing functions over a satellite link. IP traffic is carried over the proprietary
V100 link structure alongside other media. This confers a number of benefits such as improved
fragmentation, efficiency and low latency.
The V100 IP port offers bridging and static routing capability with DHCP Server/Relay functions built in. A
UDP relay function enhances this by allowing communication between a remote client and a server on the
home network. Users can now plug their laptop into the remote V100 and log in to their home network,
surf the internet and pick up E-mail.
The V100 IP port may also be used to provide IP aggregate connectivity between V100s over an
intermediate IP network thus enabling data and voice to be carried over IP. The technology is not Voice
over IP but Voice and IP.

CHAPTER 1 INTRODUCING THE V100
V100 Versatile Multiplexer Technical Manual Version 2.2
Page 13 of 231
1.2.11 Call routing
The V100 architecture supports point-to-multipoint topologies with programmable circuit routing.
Ultimately, system topologies may be designed ranging from simple point-to-point applications for mixed
voice/data services to full-mesh point-to-multipoint networks with dynamic call routing and redundant
trunk routes.
In order to assign the most efficient route for packets to reach the destination, hubs require knowledge of
the available aggregate routes to adjacent nodes in the network, together with the current bandwidth
loading on each trunk port. A Routing page tells the V100 which aggregate to use to reach the destination
port.
Each tributary channel in the network is assigned a numeric code according to its chassis, slot and channel
number, with destinations being specified for each tributary in terms of the code of the destination port. In
the case of telephony channels, either DTMF or E&M signalling digits are decoded and may be used to
directly call the destination or look up the route in a Directory to establish the destination channel. The
Directory translates real extension numbers into V100-style codes.
Calls are dynamically switched through the V100 network using the pre-programmed dialling codes.
Intelligent re-routing techniques are used to avoid congestion or link failure by selecting alternative paths.
If sufficient bandwidth cannot be found via any route, call progress tones keep the subscriber informed.
1.2.12 Dynamic Bandwidth Allocation (DBA)
The V100 may be programmed to allocate bandwidth dynamically between resources. Voice services are
granted dedicated bandwidth for the duration of the call or transmission, with remaining bandwidth
optionally transferred to the data ports. When the call ends, the bandwidth associated with it is returned
to a pool of dynamic bandwidth. All synchronous data channels configured with “DBA” clock source are
assigned to this pool, which is distributed between them in proportion to their bit rate. The V100 smoothly
adjusts the clock speeds on all DBA ports whenever a change occurs in the DBA pool.
Asynchronous data ports (including the remote management function) automatically use the DBA pool. In
the same way, channels are granted bandwidth from the pool in proportion to their bit rate but when they
become inactive and data stops flowing, the internal connection downspeeds to a nominal 2400bps and
the rest of the bandwidth is returned to the pool. The DBA pool has a lower priority than the voice or fixed
synchronous data channels and will only contain any bandwidth if these types of channel are limited by
careful configuration.
The DBA function may be invoked independently for transmit and receive, with the V100 routing engine
constantly assessing the optimum conditions even across complex networks. In this way, data networks
can make efficient use of bandwidth at all times, consistent with maximum Quality of Service (QoS) for
voice calls.

CHAPTER 1 INTRODUCING THE V100
V100 Versatile Multiplexer Technical Manual Version 2.2
Page 14 of 231
1.2.13 Control and Monitoring
The chassis has a dedicated 9-way D-type connector for management and control, labelled “Supervisor”.
This port has an RS232 interface and presents either a formatted display for network control or a terse
teletype mode for integration into the overall network management system. The facility for uploading and
downloading configuration data using script files is also provided. Refer to the “V100 Teletype Manual” for
a detailed explanation.
All of the units in a network may be controlled from the management port of any one unit, remote or hub.
This includes any chassis connected via a High Speed Channel link at any point in the network. Remote
management bandwidth is taken from the asynchronous data dynamic pool, with a minimum of 2400bps
used in times of congestion and a maximum bandwidth up to the aggregate rate when there is no other
traffic. In this way, the responsiveness of a connection to a remote unit is optimised at all times.
1.2.14 FLASH upgrading
The versatility of the system is maintained using upgradeable software running on a selection of option
cards, which may be deployed in any V100 network. In order to maintain and support equipment in the
field and also to provide upgrades and feature enhancements, all system software is held in field-
programmable FLASH memory. The software release programmed in the factory contains a loader kernel,
which can communicate with a PC-based download utility. When an upgrade is requested, Vocality
International Ltd will supply the new target software suite and the downloader, which runs under
WindowsTM 95/98, 2000 or XP. The target code is serially downloaded into the unit via the supervisor port,
which will then boot and run the new code. The integrity of the unit is preserved at all times such that the
original code may be restored in the event of a problem occurring during the process.
Units may be password-protected. To maintain the security this provides, the downloader utility requires
that the correct read/write password is entered before downloading commences.
The V100 has seen three platform enhancements since its launch, each of which requires specific
hardware support in the operating software. To ensure that the new software is a compatible revision, the
downloader can automatically select the right file if a check box is ticked. Alternatively the file may be
selected manually.
The download utility also allows units to be upgraded remotely by specifying the Node ID.
For full instructions on using the FLASH utility, refer to Application Note AN019.

1.3 Topologies
1.3.1 Star Networks
The ability to configure multiple aggregate ports allows Star network topologies to be built with the V100,
ranging from simple point-to-point systems at one extreme to a cluster with up to 10 remotes per chassis
at the other. Connections may be permanent or dynamic, the choice being made by the nature of the
traffic. Data traffic will require fixed routes, whereas voice traffic will usually be switched. Here, if in-band
signalling is specified, routes will be defined with reference to a directory of network addresses, which
relate to the decoded dialing digits.
Connections may be established between any ports in the network, including the hub. When indirect or
onward routes are implemented at the hub, voice/fax or MPEG data remains compressed.

1.3.2 Mesh Networks
The expansion capabilities of the V100 make it an ideal foundation for a full-mesh network. Since any
data port may be used as an aggregate link, complex networks may be designed which exploit the
versatility of the system. Point-to-point connections for data channels, ISDN basic rate extension or MPEG
audio broadcast happily co-exist alongside dynamic voice traffic or asynchronous data links.
When used in conjunction with a DAMA controller, the dynamic bandwidth and advanced compression
techniques used by the V100 can produce a highly efficient and flexible satellite communications system.

1.3.3 Broadcast Networks
The V100 may be used in broadcast applications, where many remote units may wish to select a receive
channel from a large outbound carrier. Often there is also a requirement for a return carrier from each
site, which can be transmitted back to the hub. The flexibility of the unit is such that this kind of network
topology can be used with all of the voice, data and IP facilities to provide a large network of users with
fully integrated comms services.
It may also be desirable to connect various dedicated channels at the same time as these selectable
broadcast services. The V100 may be configured to provide any combination of connectivity. When used
with the multiple configuration stores, switching from one programme setup to the next is simple.

The Analogue Voice/FAX Motherboard (VI68701) is fitted with a number of jumper links which configure
the hardware according to the application. These are set when the card is commissioned and should not
need to be changed thereafter. All other configuration changes are made by software selection.
This card supports four fully independent voice/FAX channels. The ring voltage power supply module fitted
to the motherboard has sufficient capacity for driving all eight channels and does not need to be
upgraded.
The layout and white component identifications on the Voice/FAX Daughterboard are identical to those on
the Motherboard to aid location when changing jumper settings.
