Receiving the Equipment
2.1 Initial Inspection
When the shipment of your MX250 system arrives, inspect the shipping boxes for external
damage, and record any discrepancies. Save the boxes and packing material in case you need to
ship the system to another facility. Always retain the packing materials if you suspect that part of
the shipment is damaged—the carrier may need to inspect them.
Warning Do not attempt to use the equipment if it appears damaged. Immediately report
the damage to Zultys or a local Zultys sales representative.
Chapter 2
2.2 Shipment Contents
2.2.1 Unpacking Boxes
If the boxes have not been damaged in transit, unpack them carefully. Ensure that you do not
discard any accessories that may be packaged in the same box as the main unit. Take care when
handling the MX250.
Caution Do not drop or jolt the MX250. The hard disc inside the MX250 is designed for
continuous operation, but is fragile until installed. If you allow the MX250 to receive
a hard knock, you can cause irreversible damage to the hard disc.
2.2.2 Verify Content
Upon delivery of your system, inspect the packing list, and confirm that all items listed on that
note were received. You may not be able to verify delivery of firmware options until after you
install your system. Compare the packing slip with your purchase order.
Ensure that the accessories listed in figure 2-1 are present in the shipment.
Ensure that there are no discrepancies in the shipment and then prepare the site as described in

2.4 Returning Items for Repair or Replacement
2.4.1 Warranty Coverage
Zultys provides a warranty only through distribution channels. If you are an end user, consult the
reseller or distributor who has sold you the product for complete terms of the product that you
have purchased. Zultys requires that its distributors provide a standard warranty that is one year
in duration, and that complies with the local laws and expectations of the country in which you
reside.
Before returning merchandise for repair or replacement, you must ensure that the items are
under warranty. If you are unsure about the warranty of your merchandise, call your supplier or
a local Zultys sales representative for clarification. Contact your supplier for a return merchandise
authorization (RMA) number before returning any merchandise; this includes equipment
covered under warranty.
For merchandise not under warranty, you will be charged for a repair if the item is returned to
the factory. Call your supplier for pricing on an extended warranty for your merchandise.
2.4.2 Describing the Problem
If you are returning equipment for service, attach a tag or sheet of paper to the equipment giving
the following details:
2. Receiving the Equipment
• your company or institution’s name, address, and phone number
• the main person to contact, an alternative contact, and their phone numbers if different from
the main phone number
• the return shipping address and any special shipping instructions
• the model number and serial number of the equipment being returned
• a description of the failure (If failure is intermittent, describe its frequency and special
conditions that initiate the failure.)
• any additional comments
2.4.3 Accessories
Do not return any of the accessories with the equipment unless you suspect that it is faulty. If you
return an accessory, place a tag on it that clearly identifies it as yours, and briefly explain the
problem.
2.4.4 Packing
Wherever possible, use the original packing materials to ship the equipment. If these are not
available, containers and cushioning material similar to those originally used are available from
Zultys.
If it is inconvenient to obtain supplies from Zultys, use a strong, double-walled shipping carton.
Place about 70 mm (3 in) of cushioning material around all sides of the equipment.
Zultys is not responsible for any damage that occurs during shipment back to your supplier or to
the factory.

MX250 Hardware Manual
2.4.5 Shipping
Obtain from your nearest Zultys sales or service representative the correct address to which you
should return the equipment. Clearly mark the container with Zultys’ address and your own
address. Ship the package prepaid and insured to Zultys.
The method of shipment which Zultys will return repaired merchandise back to your facility will
be the same method by which you shipped the merchandise to Zultys. For example, if you
shipped merchandise to Zultys by ground shipment, Zultys will return the merchandise to you
by ground shipment. If the merchandise must be repaired and returned to you as soon as
possible, you must arrange for the merchandise to be shipped to Zultys by overnight shipment.
2.4.6 Correspondence
In any correspondence subsequent to the return of equipment, always refer to the equipment by
model number, serial number, and the RMA number assigned.

MX250 Hardware Manual
3.4.1.2 RJ45 Pin Assignment
All 10/100Base-T Ethernet ports can be routed to a patch panel or to a punch down block for
fanning out to the proper destination. All ports use the RJ-45 connectors. Each circuit can
auto-detect CAT5 cable configuration (straight or crossover) and adapting accordingly.
Ethernet cable wiring must comply with EIA/TIA 568A for the CAT5 10/100Base-T Ethernet. Some
cable suppliers reference EIA/TIA 568A and others reference 568B. The difference is that the green
and orange pairs are terminated to different pins, however, the assignment of pin to signal are
exactly the same on both references. Crossover cables comply with EIA/TIA 568A in all aspects
except signals on pins 1 and 3 at one end appear on pins 2 and 6 at the other end.

3.5 Console Mode
Console mode provides a method of to accessing the MX250 in a known, predefined state.
Console mode is used to initially configure the IP address of the system or to recover a lost or
unknown IP address. Putting the MX250 in console mode during power up.
Before putting the MX250 into console mode, you should disconnect the Ethernet ports from your
system. This will ensure that there are no conflicts with other devices on your network.
Important Ensure that the Ethernet cables are disconnected from the MX250 before entering
console mode. Failure to do so may disturb other devices on the LAN.
When the MX250 is in console mode, you can connect a computer to the Second Ethernet Port
(item 8 in figure 3-2 on page 12). The IP address used to access the MX250 depends whether the
MX250 was placed in console mode during normal operation or during power up.
3.5.1 Console Mode Activated During Power Up
Pressing the Console button during power up sets the console port to a known fixed IP address
so you can communicate with the MX250.

Preparation
4.1 Introduction
This chapter explains:
• guidelines for selecting a site
• the tools required for installation
• types of cables for the voice and data circuits
The MX250 is designed to be permanently installed within a network room in a 19" equipment
rack. You must carefully install the MX250 system to ensure its proper operation.
Chapter 4
Warning The MX250 is designed to be installed by qualified personnel only. Installation by
unqualified individuals may result in bodily injury and damage to the MX250 and
surrounding equipment.
Warning This equipment is to be installed and maintained by service personnel only as
defined by AS/NZS 3260 Clause 1.2.14.3 Service Personnel.
Warning The MX250 must be installed in a secure location that has access restricted to
qualified personnel only. Placing the MX250 in a location accessible by unqualified
individuals may result in bodily injury and damage to the MX250 and surrounding
equipment.
4.2 Selecting a Site
The following criteria must be considered when selecting a site for your MX250 system:
21
Page 26
MX250 Hardware Manual
4.2.1 Earth Ground
The resistance between the equipment frame and earth ground (per UL 60950, paragraph 2.6.3.3)
should be less than 0.1 Ω. An adequate earth ground is normally implemented with a copper rod
(about 15 mm or 0.6" diameter) driven at least 4 m (12 ft) into moist soil. Improve conductivity by
adding salt or magnesium sulphate to the soil surrounding the rod to a depth of 200 mm (0.6 ft);
periodic replenishing may be required.
4.2.2 Temperature
Install the MX250 where the temperature remains between 0°C and 40°C.
Warning If you install the MX250 in an environment where the temperature is outside the
range 0°C ~ 40°C, this may result in bodily injury and damage to the MX250 or
surrounding equipment. You will also void your warranty.
4.2.3 Ventilation
The MX250 requires space on both sides for ample air flow. The internal fans move the air from
left to right as you look at the front of the equipment.
Important Do not cover the slots and openings on the equipment. These are provided for
ventilation and protection against overheating.
4.2.4 Cable Lengths
Cable placement to associated equipment is an important site criteria. Figure 4-1 shows the
minimum and maximum length of any cables that you connect to the MX250.
Circuit Connector Minimum Distance Maximum Distance
T1 or E1 RJ45 0 1.8 km (6000 ft.)
Analog RJ11 0 1 km (3000 ft)
BRA S/T RJ45 5 m (15 ft) 25 m (75 ft)
10/100BaseT RJ45 0 100 m (300 ft)
48 V battery Molex Mini Fit 0 3 m (10 ft)
Audio 3.5 mm 0 3 m (10 ft)
Figure 4-1 Minimum and Maximum Cable Lengths
The distance listed in the table for the T1 or E1 circuits is the maximum distance between the
MX250 chassis and the nearest T1 or E1 signal repeater. The actual cable used to connect to the
demarcation point may be significantly shorter.
The battery input to the MX250 uses a special connector. Zultys supplies a cable to connect to it,
the length of which is shown in the table.
22
Page 27
4.2.5 Other Site Requirements
Select a site where liquids or objects will not fall onto the equipment and that foreign objects will
not be drawn into the ventilation holes.
4.3 Power Requirements
The MX250 uses ac power as its primary power source. You can connect the BPS12 to the MX250
to provide continued operation in the event of loss of ac power.
Warning The MX250 is inoperable when ac power fails and you have not installed a battery
backup system, or when the power of the battery backup system is exhausted.
4.3.1 AC input
The total ac power input on the MX250 is 100 W, which includes power for ringing and battery
feed to analog telephones and fax machines.
The MX250 has a universal ac input that you can connect to a standard electric outlet (100 Vac to
240 Vac, 47 Hz to 63 Hz).
4. Preparation
4.3.2 –48 V Battery
Connecting a BPS12 battery power supply to the MX250 continues operation in the absence of ac.
Zultys recommends using the BPS12 as the external supply in addition to connecting to the ac
power source. Connect to the BPS12 as described in the BPS12 Hardware Manual. The BPS12
battery unit sold by Zultys requires 3 RU of rack space and a separate ac source.
Warning You must use the BPS12 battery system provided by Zultys, or use a battery source
that is supplied by a Listed or Certified power supply providing SELV power. This
is required because the –48 Vdc directly powers the SELV of the system.
The BPS12 battery unit sold by Zultys requires 3 RU of rack space and a separate ac supply.
Important Zultys strongly recommends use of the BPS12 for all installations of the MX250.
During power outages, this provides a dc source from which the MX250 can
detect capacitive levels. This allows the MX250 time to initiate a proper shutdown
of its database.
4.3.3 Uninterruptable Power Supply (UPS)
Although connecting the ac input to a UPS allows the system to operate during a power outage,
Zultys does not recommend this solution since most UPS devices do not provide the longevity
demanded by telecommunications applications. Most UPS devices are scaled too small and can
only providing a short standby duration.
23
Page 28
MX250 Hardware Manual
The MX250 monitors the battery voltage, which allows the system to provide an alert or shut
down the system when battery voltage declines below a specified value. The MX250 has no
provision for monitoring the voltage of the component batteries of an external UPS.
4.4 Electrostatic Discharge (ESD) Precautions
Almost all electronic components can be damaged by ESD during handling. Component damage
can occur at ESD voltages as low as 50 V. A person walking across a nylon carpet can easily
generate voltages in excess of 5,000 V.
Observe the following guidelines to help prevent ESD damage when installing or servicing the
MX250 system or any other electronic device.
• Assemble or disassemble equipment only in a static-free work area.
• Use a conductive work surfaces (such as an antistatic mat) to dissipate static charge.
• Wear a conductive wrist strap and lab coat to dissipate static charge accumulation.
• Minimize handling of assemblies and components.
• Keep replacement parts in their original static-free packaging.
• Remove all plastic, foam, vinyl, paper, and other static-generating materials from the
immediate work area.
• Use tools that do not create ESD.
In addition to these precautions, do not handle connector pins or touch onboard components to
avoid contamination.
Caution You can easily damage the MX250 by failing to follow these instructions. You may
delay installation, or cause the equipment to prematurely fail. Such failure may lead
to a disruption of the service provided by the equipment. You may also void your
warranty.

Important You must read the section on site selection and preparation before starting to
install the MX250. Refer to chapter 4, starting on page 21.
Chapter 5
5.2 Equipment Rack
Zultys recommends installing the MX250 in the same secured wiring closet as the networking
equipment to which it connects. Devices typically connected to the MX250 include the firewall,
the LAN switch, the battery power system, and the provisioning computer.
All connections to the MX250 system are made at the rear panel. Leave space next to the rear
panel for cables and for personnel installing the system.
Warning The MX250 system must be properly grounded (earthed). When the equipment is
mounted in an equipment rack, the rack must be connected to ground (earth). See
section 4.2.1 on page 22 for details on the proper grounding technique.
Warning Ensure that the rack is properly mounted to the floor or has properly fitted
stabilizers so that it cannot move and will not tip over. If the rack tips over, it may
cause you bodily injury and may damage the equipment.
When mounting equipment in the equipment rack, place the equipment at the bottom of the rack
if it is the only equipment in the rack. If you mount the equipment in a partially filled rack, load
the rack from the bottom to the top with the heaviest equipment at the bottom of the rack.

Glossary
10/100Base-T. A physical media that can operate as 10Base-T or 100Base-T.
10Base-T. A physical media specified by the IEEE 802.3 standard for supporting Ethernet with a
maximum transmission rate of 10 Mb/s. 10BaseT consists of copper twisted-pair cable normally
used for wiring ordinary telephones. Ethernet is a common technology used for connecting
computers into a local area network (LAN).
100Base-T. A local area network transmission standard that supports a data rate of 100 Mbps. Also
known as Fast Ethernet; similar in function to 10BaseT.
Authorization. The process of verifying the identity of a person or device. Authentication is
commonly performed through logon passwords; knowledge of the password is assumed to
guarantee that the user authenticity. Internet business and many other transactions may require
a more stringent authentication process, such as the use of digital certificates issued and verified
by a Certificate Authority as part of a public key infrastructure. Logically, authentication precedes
authorization, although they may often seem to be combined.
Bridge. A device that connects network segments that use the same protocol, such as Ethernet. A
bridge forwards traffic between network segments on the basis of datalink layer information;
these segments would require a common network layer address.
Ethernet. The most widely-installed local area network (LAN) technology. Originally developed
at the Xerox Corporation Palo Alto Research Center, Ethernet is specified in the IEEE 802.3
standard. Ethernet is a best-effort delivery system that uses CSMA/CD technology. Ethernet can
be run over a variety of physical media, including coaxial, twisted pair, and fiber optics.
Firewall. A device, located at a network gateway server, that protects the resources of a private
network from external entities. Typically comprises a set of related programs or a dedicated
computer equipped with such security features as logging, reporting, alarms, and a control
mechanism.
Foreign Exchange Office (FXO). An analog interface that connects to the Public Switched
Telephone Network (PSTN) central office and is the interface offered on a standard telephone.
Foreign Exchange Station (FXS). An analog interface that connects directly to a standard
telephone and supplies ring, voltage, and dial tone.
Frame R elay. A telecommunication service designed for cost-efficient data transmission of
intermittent traffic between local area networks (LANs) and between end-points in a wide area
network (WAN). Frame relay places data into in variable-size units called frames and speeds up
the overall data transmission by leaving all necessary error correction (data retransmission) up to
the end-points.
47
Page 52
MX250 Hardware Manual
Gateway. A network point that serves as an entrance to another network. Computers that control
traffic within an enterprise’s network or at the local Internet Service Provider (ISP) are gateways.
IP datagrams are transferred from network to network through gateways until it reaches its final
destination. See Router.
Hub. A hub network topology consists of a backbone (main circuit) to which a number of
outgoing lines can be attached, each providing at least one connection port for attaching devices.
As a network product, a hub may include a group of modem cards for dial-in users, a gateway
card for connections to a local area network, and a line connection.
Hypertext Transfer Protocol (HTTP). An application layer protocol that defines a set of rules for
exchanging files (text, images, sound, video, and other multimedia files) on the Internet.
Described by RFC 2068.
Incoming call. A call originated by a source that is external to the enterprise.
Internet. A worldwide computer network system in which users at any one computer can, with
permission, exchange information from any other computer and sometimes talk directly to users
at other computers; also known as the “Net.” Originally designed by the Advanced Research
Projects Agency (ARPA) of the U.S. Defense Department in 1969 so that a communication signal
could withstand a nuclear war and serve military institutions worldwide. First known as the
ARPAnet, the internet has evolved into public, cooperative, and self-sustaining facility accessible
to billions of people worldwide.
Internet Engineering Task Force (IETF). The organization that defines standard Internet operating
protocols such as TCP/IP. The IETF is supervised by the Internet Society Internet Architecture
Board (IAB). IETF members are drawn from the Internet Society's individual and organization
membership. Standards are expressed in the form of Requests for Comments (RFCs).
Internet Protocol (IP). A network layer protocol that sends datagram packets between Internet
nodes. IP is a connectionless protocol, implying that there is no continuing connection between
communicating endpoints. IP provides addressing, type-of-service (ToS) specification, security,
fragmentation and reassembly features. The most widely used IP version is Internet Protocol
Version 4 (IPv4). The ZIP 4x4 phone supports IP as defined in RFC 791.
Internet Protocol Version 6 (IPv6). The latest level of the IP that is included in many projects,
including the major computer operating systems. The most obvious improvement in IPv6 over
IPv4 is the lengthening of IP addresses from 32 bits to 128 bits. All servers that support IPv6 will
also support Internet Protocol Version 4.
Intranet. A restricted-access network that works like the Web, but isn't on it. Usually owned and
managed by a corporation, an intranet enables a company to share its resources with its
employees without making available confidential information to everyone with Internet access.
IP Address (version 4). A 32-bit number that identifies each sender or receiver of information sent
across the internet. An IP address has two parts: the network identifier and the identifier of a
specific device on the network. On the Internet itself – between the router that moves packets
between points along the route – only the network part of the address is examined.
IP Security (IPSec). Security standard produced by the Internet Engineering Task Force (IETF); a
protocol suite that provides all necessary elements for secure communications-authentication,
integrity, and confidentiality-and makes key exchange practical even in larger networks.
48
Jitter. Jitter is the deviation in some aspect of the pulses in a high-frequency digital signal or the
period frequency displacement of the signal from its ideal location. The MX250 utilizes Jitter
Buffers to compensate for jitter.
Page 53
Local Area Network (LAN). A group of computers and associated devices that share a common
communications line and the resources of a single processor or server within a limited geographic
area, such as an office building. 10BaseT Ethernet is the most commonly used form of LAN. A
hardware device called a hub serves as the common wiring point, enabling data to be sent from
one machine to another over the network. LANs are typically limited to distances of less than 500
meters and provide low-cost, high-bandwidth networking capabilities within a small
geographical area.
Media Access Control (MAC) Address. A hardware number that uniquely identifies a computer or
other device. Within an Ethernet configuration, the MAC address is a 6-octet address assigned to
the network interface card. When your computer is connected to the Internet, a correspondence
table relates your IP address to your computer's physical (MAC) address on the LAN. The MAC
address is used by the Media Access Control sublayer of the Datalink Control (DLC) protocol
layer. Each physical device type has a different MAC sublayer.
Network Interface Card (NIC). A circuit board or card that is installed in a computer for the
purpose of connecting the computer to a network. Personal computers on a LAN usually contain
a NIC designed for a specific LAN transmission technology, such as Ethernet.
Network Time Protocol (NTP). A protocol that synchronizes computer clocks on an IP network.
Described by RFC 1305.
Per-Hop Behavio r. The differential treatment an individual packet receives while being routed
through a network, as implemented by queue service or queue management disciplines. These
per-hop behaviors are useful and required in network nodes to deliver differentiated treatment
of packets regardless of end-to-end construction or intra-domain services. Per-Hop behavior is
discussed in RFC 2474 and Per-Hop Identification codes are defined in RFC 3140.
B.
Point-to-Point Protocol (PPP). A protocol that defines a communication method between two
computers using a serial interface. Typically used to connect a personal computer to a server
through a phone line.
Proxy Server. A server that acts as an intermediary between a workstation and the Internet to
provide a caching service and ensure security and administrative control for the enterprise. The
proxy server is invisible to the workstation; all Internet requests and returned responses
involving the workstation appear to be directly with the addressed Internet server.
Public Switched Telephone Network (PSTN). The world-wide collection of voice-oriented public
telephone networks. Also referred to as Plain Old Telephone Service (POTS).
Quality of Service (QoS). The concept that transmission rates, error rate, and other characteristics
over a network or the Internet can be quantified, improved, and guaranteed (to a certain extent)
in advance. QoS is particularly concerned with the continuous transmission of high-bandwidth
video and multimedia data.
Real-Time Transport Control Protocol (RTCP). The protocol companion to RTP that provides
error, session control, and identification data about a transport session. Described by RFC 1889.
Real-Time Transport Protocol (RTP). An Internet protocol standard that specifies a method for
programs to manage the real-time transmission of multimedia data over unicast or multicast
network services. RTP combines its data transport with an control protocol (RTCP), which makes
it possible to monitor data delivery for large multicast networks. The ZIP 4x4 phone supports RTP
as a media channel for voice and video applications as described in RFC 1889.

Page 54
MX250 Hardware Manual
Repeater. A device that receives a digital signal on a transmission medium and regenerates the
signal for the next leg of the medium. Repeaters overcome attenuation losses caused by free-space
electromagnetic-field divergence or cable loss over electromagnetic media. A series of repeaters
facilitates the extension of a signal over long distances.
Request for Comments (RFC). A formal document issued by the Internet Engineering Task Force.
Some RFCs are informational in natural while others become Internet standards. RFCs are the
result of committee drafting and subsequent review by interested parties. No further comments
or changes to an RFC are permitted once it becomes an Internet standard; changes to internet
standards are enacted through subsequent RFCs that supersede or elaborate on all or parts of
existing RFCs.
Reverse Address Resolution Protocol (RARP). A protocol by which a physical machine in a local
area network can request its IP address from a gateway server’s Address Resolution Protocol table
or cache. RARP is described in RFC 903.
RJ-45. A single-line digital transmission interface. Resembling a standard phone connector, an
RJ-45 connector is twice as wide (with eight wires) and is used for connecting computers to local
area networks (LANs) or phones with multiple lines.
Router. A device that determines the next network point to which a data packet should be sent on
the to its final destination. Routers also act as traffic cops, allowing only authorized machines to
transmit data into the local network so that private information can remain secure. In addition to
supporting these dial-in and leased connections, routers also handle errors, maintain network
usage statistics, and handle security issues.
Security Parameters Index (SPI). A hexadecimal value which uniquely identifies each tunnel.
Server. A computer program or device that provides services to other computers.
Server Farm. A network where clients install their own computers to run Web servers, email, or
any other TCP/IP based services they require, making use of leased permanent Internet
connections with 24-hour worldwide access. Instead of using expensive dedicated-line
connections to various offices, servers can be placed on server farm networks to provide
high-speed Internet access for a fraction of the cost of a leased line.
Session Description Protocol (SDP). An ASCII-based protocol that describes multimedia sessions
and their related scheduling information, including information transport session participant
port numbers and contact addresses. The ZIP 4x4 phone uses SDP for session descriptions as
documented in RFC 2327.
Session Initiated Protocol (SIP). An Internet standard protocol that defines a method of initiating
an interactive user session involving multimedia elements, such as voice, chat, gaming, video,
and virtual reality. SIP is a request-response protocol that deals with requests from clients and
responses from servers through any transport protocol, such as UDP or TCP. Described by RFC
3261, SIP can establish, modify, or terminate multimedia sessions or Internet telephony calls.
Simple Network Time Protocol (SNTP). A protocol that synchronizes computer clocks on an IP
network. Similar to NTP with fewer features. Some IP phones use SNTP for their date and time
synchronization functions. Described by RFC 2030.
SIP Endpoint. An internet host that understands the SIP protocol.
SIP Registrar. A SIP Registrar is a UAS that responds to REGISTER requests and maintains a list
of bindings that are accessible to proxy servers and redirect servers within its administrative
domain.
50
Page 55
SIP Server. A network device that performs special functions at the request of SIP endpoints.
Servers typically act in response to SIP endpoint requests, but can also initiate functions on their
own. RFC 3261 defines three types of SIP servers: SIP Proxy servers, Redirect servers, and
Registrar servers.
Spanning Tree Protocol (STP). When constructing a network, a second bridge between two
network segments is often installed as a backup. The Spanning Tree Protocol allows these bridges
to exchange information so that only one of them will handle a given message sent between two
computers within a network. Described by RFC 2878, the Spanning Tree Protocol prevents the
condition known as bridge loop.
Subnet Mask. A number that, when applied to an IP address, can identify the subnetwork where
the address resides. For example, within a class B network, a subnet mask of 255.255.255.0
specifies that the first two portions of the decimal dot format are the network number, while the
third portion is a subnet number. The fourth portion is the host number. A subnet mask of
255.255.0.0 species a class B network that does not have a subnet.
Switch. A network device that selects a path or circuit for sending a unit of data to its next
destination. A switch may also include the function of the router. A switch is generally a simpler
and faster mechanism than a router, which requires knowledge about the network and how to
determine the route. A switch is usually associated with layer 2 of the OSI communications
model.
B.
System Controller (SC). One of the boards inside the MX20. It is connected to a hard disc that
stores all of the application software for the MX250 and upon power on, forwards the software to
the other boards in the system. This board also has the console port directly connected to it so that
you can always communicate with the system. The board also controls the LEDs at the rear of the
system that indicate the nature of a problem if the MX250 is unable to start up.
Three-Way Handshake. A triple-exchange of data packets that establishes a TCP connection. The
Three-Way Handshake transpires as follows:
1. The initiator sends a SYN (synchronize/start) packet.
2. The recipient replies with a SYN/ACK (synchronize/acknowledge) packet.
3. The initiator responds with an ACK (acknowledge) packet.
At this point, the connection endpoints are established and data transmission can commence.
Transmission Control Protocol (TCP). A set of communications protocols that, when used with
Internet Protocol (IP), support peer-to-peer connectivity functions for both local and wide area
networks. TCP/IP is a communications protocol which allows computers with different operating
systems to communicate with each other and controls how data is transferred between
computers on the Internet.While IP handles the actual delivery of data, TCP tracks the data
packets into which a message is divided for efficient routing through the internet. The ZIP 4x4
phone supports TCP as described by RFC 793.
Tr us ted Net wor k. Networks inside your network security perimeter. Only known and approved
sources are allowed access to a trusted network.
Tu n n e l in g . The transmission of data intended for use only within a private network through a
public network in such a way that the routing nodes in the public network are unaware that the
transmission is part of a private network. Tunneling is generally done by encapsulating the
private network data and protocol information within the public network transmission units so
that the private network protocol information appears to the public network as data. Tunneling
allows the use of the Internet, which is a public network, to convey data on behalf of a private
network.

Universal Resource Locator (URL). A standard method of specifying the location of an internet
resource. Also referred to as a location or address, URLs specify the location of files on servers. A
general URL has the syntax protocol://address. For example, http://www.zultys.org/index.html
specifies that the protocol is http and the address is www.zultys.org/ index.html.
Unshielded Twisted Pair (UTP). Also known as 10BaseT. This is the standard cabling used for
telephone lines. It is also used for Ethernet connections.
Untrusted Network. Networks that are outside of your security perimeter; Private and shared
networks over which you have no control over the administration or security policies. Firewalls
deal with the problem of communicating with these networks while protecting your trusted
network.
User Agent. A SIP logical entity that can act as both a user agent client (UAC) and user agent server
(UAS). The role of UAC and UAS, as well as proxy and redirect servers, are defined on a
transaction-by-transaction basis. For example, the user agent initiating a call acts as a UAC when
sending the initial INVITE request and as a UAS when receiving a BYE request from the calling
station. Similarly, the same software can act as a proxy server for one request and as a redirect
server for the next request.
User Agent Client. A SIP logical entity that creates a new request, and then uses the client
transaction state machinery to send it. The role of UAC lasts only for the duration of that
transaction; if a piece of software initiates a request, it acts as a UAC for the duration of that
transaction. If it receives a request at a later time, it assumes the role of a user agent server to
process that transaction.
User Agent Server. A SIP logical entity that generates a response to a SIP request. The response
accepts, rejects, or redirects the request. This role lasts only for the duration of that transaction; if
a piece of software responds to a request, it acts as a UAS for the duration of that transaction. If it
generates a request later, it assumes the role of a user agent client to process that transaction.
User Datagram Protocol (UDP). A communications protocol that offers a limited amount of
service when messages are exchanged between computers in a network that uses IP. An
alternative to TCP, UDP uses the IP to transfer a data unit between computers without dividing it
into packets and reassembling it at the other end. Because UDP does not provide the sequencing
of packets, the application program that uses UDP must be able to verify that the entire message
has arrived in the proper order. UDP is in the Transport Layer (or Layer 4) of the OSI
communication model. The ZIP 4x4 phone supports UDP as defined in RFC 768 for SIP signalling.
Virtual Local Area Network (VLAN). A Local Area Network that maps workstations on a logical
basis (such as department or primary application) rather than by physical location. VLAN
members are not identified by their location on a physical subnetwork but through the use of tags
in the frame headers of their transmitted data. VLANs are described in the IEEE 802.1Q standard.
Virtual Private Network (VPN). A method of using the Internet to provide remote offices or
individual users with secure access to their organization's network. A virtual private network can
be contrasted with an expensive system of owned or leased lines that can only be used by one
organization. The goal of a VPN is to provide an organization with the same capabilities, but at a
much lower cost. VPNs are possible because of technologies and standards such as tunneling,
screening, encryption, and IPSec.
Wide Area Network (WAN). A geographically dispersed telecom network. Although a WAN may
be privately owned, the term usually implies the inclusion of public networks.
