Chapter 2 Installing VIP

This chapter gives information on how to install VIP.

2.1 Network Requirements

For VIP successfully operate in your network, your network must meet the following requirements:

1. A working 10/100 Base-T Ethernet. VIP connects to Internet via an Ethernet LAN.

2. IP network that supports gateway, and subnet mask. You’ll need a static IP address to assign
VIP.

2.2 Installing VIP

VIP can be used in a desktop configuration or mounted in a standard 19-inch rack enclosure (VIP­000 only). Ensure that VIP is placed in a clean, well-ventilated, and vibration-free environment.

When VIP is placed on a desktop, be certain that the unit is placed on a sturdy, flat surface, near a
grounded power outlet. At least three inches of clearance must be provided on both sides of VIP
for well ventilation.

2.3 Installing the telephony interface module (VIP-000 only)

VIP allows the installation of up to two TIMs. The following steps illustrate how to install a TIM:

1. Unfasten the two screws holding the cover of the TIM slot A on the rear panel.

2. Remove the cover.

4. Before proceeding further, wear a grounded wrist strap.

5. Remove the TIM from its static-free bag. Holding the module such that the metal

bracket is facing toward you.

6. Carefully align the edge of the module facing away from you with the slide-in guide in-

side VIP, and insert the module into the slide-in slot until it is fully sited.

7. Fasten the screws on the module.

8. Repeat step 1 through 6 for slot B if you have two TIMs. If you have only a single TIM,

be certain to install it in slot A, otherwise, VIP won’t function.

2.4 Connecting to the telephony devices

VIP-000 supports three types of TIM. One is FXO, FXS and the other is E&M. Each module has
four ports for connecting to telephony devices. VIP-200 equips two FXS interface for connecting to
regular analog telephone sets or FAX machine. VIP-400 equips two FXO and two FXS interfaces to
have the great flexibility of PBX connection (FXO), and telephone or FAX machine connection

(FXS). VIP-400FS equips four FXS interfaces telephone set or FAX machine connections (FXS).
VIP-400FO equips four FXO interfaces to have the great flexibility of PBX connection (FXO)

VIP-FXO module is designed for connecting to PBXs (extension line) or central office switches (CO
line).

VIP-FXS module is designed for connecting to analog telephone sets or G3 fax machines. Con­necting the telephony devices to the appropriate RJ11 ports on the TIM.

VIP-E&M module is designed for connecting to equipment (such as PBX or channel bank) providing
the tie-line connection, type V, 4-wire. Connecting the tie-line port to the appropriate RJ45 port on
the TIM.

Warning: connection of incorrect telephony devices to the ports on the TIM can cause permanent
damage to the TIM and/or VIP.

2.5 Connecting to the Network

The RJ45 network port on the front panel supports 10/100 Mbps half-duplex connection to Ethernet
Network. You can use either category 3 or 5 straight-through UTP cable for 10 Mbps connections,
but use Category 5 for 100 Mbps connections. To connect to Ethernet, insert one end of the
Ethernet cable to the RJ45 port on the front panel of VIP and other end of the cable to an Ethernet
switching hub or repeater hub.

2.6 Providing Power to VIP

To provide AC power to VIP complete the following steps:

1. Turn the power switch on the rear panel of VIP to the off position.

2. Connect one end of the power cord that came with VIP to the power receptacle on the rear
panel.

3. Connect the other end of the power cord to an AC power outlet.

4. Turn the power switch on. VIP will perform power on self-test. After completing the self-test,
the SYSTEM LED blinks continuously and the TIM indicators on the front panel will turn on.

2.7 Assigning IP address to VIP

The IP address is the unique logical address identifying each IP node, such as VIP, on an IP net­work. An IP address is a 32-bit number expressed as four decimal numbers from 0 to 255 sepa­rated by periods. VIP needs a static IP address and be aware of the subnet mask and default
gateway (typically a router) of your network to be able to send to and receive data from the IP net­work. Consult your network manager to obtain a unique and static IP address for VIP, the IP subnet
mask and default gateway of your network, and fill out the work sheet in Appendix D before config­uring the gateway. Procedures for assigning IP address, default gateway and subnet mask is avail­able in Chapter 4.

VIP User’s Manual

Chapter 3 VIP Concepts

VIP enables the transmission of voice and fax traffic over any IP network by digitizing voice and fax
signals, encapsulating the information within IP packets, and then sending the packets across the
IP network

3.1 How VIP Operates

1. The TIM inside VIP digitizes analog voice signals at 8 Kbps.

2. VIP system software handles the:

Ÿ Capture of telephone number presented as DTMF tones.
Ÿ Mapping the telephone number to the IP address of remote VIP.
Ÿ Setting up calls with remote VIPs utilizing H.323 call control protocol.
Ÿ Digitizing, compressing and encapsulating the voice into IP packets and transmission of the

IP packets onto the Ethernet LAN.

3. A router attached to the LAN forwards the IP packets across the WAN, where they will be re­ceived by another VIP at the remote.

4. The process is reversed at the remote VIP.

3.2 ATPM

To allow you to easily dial a telephone or fax on the network, VIP maps a series of dialed digits to
the IP address of the remote VIP whose phone or fax you are calling. This mapping information is
contained in a database inside each VIP called the dial plan.

Based on the dial plan the Address Translation and Parsing Manager (ATPM) inside VIP translates
telephony numbers to IP addresses of remote VIPs. The ATPM collects telephone number dialed
by users, decides whether the dial string is part of the dial plan and, if it is, maps it a remote VIP.
When the call is set up to the destination, a substring of the original dial string will be sent along to
the remote VIP.

3.3 Destination

The destination is where a call is terminated. Typically, for inbound calls from IP network, VIP ter­minals the call at one of the telephony ports. The destination for the call is the telephony port where
the call terminated. For calls initiated from telephony ports, VIP forward the call to a remote VIP via
IP network, and the remote VIP terminal the call. The destination of the call is the remote VIP.

3.4 Hunt Group

Instead of directly mapping a phone number to a destination, the ATPM first maps the phone num­ber to a group of destinations known as a Hunt Group. A hunt group is a group of destinations that
are equivalent. For example, the customer support group of a company might have 20 peo-

ple who can handle support calls. Access to customer support is through a single phone
number but the next available support person is actually connected upon each incoming
call. These 20 phones would be configured as a hunt group. A hunt group consists of a
phone number and a list of destinations (members of the group). When an incoming phone

number matches the phone number of the hunt group, VIP attempts to terminate the call at each of
the destinations in the hunt group, one at a time until a call is successfully completed.

Every destination that can be reached by dialing a phone number is a member of at least one hunt
group. When an address is presented to ATPM for lookup, the output is a hunt group ID number.
As a second step, the hunt group ID is presented to ATPM to get the list of members. To effectively
bypass the hunt group feature, simply make a unique hunt group for each destination and one
member in each hunt group.

3.5 Dial Plan

The dial plan is a database inside VIP for the ATPM to map telephony numbers users dialed to the
IP address of remote VIPs. The dial plan consists of the destination table, hunt group table and the
address table. Users need to setup these tables, so that VIP knows how to setup calls with remote
VIPs.

Address Table

The address table maps a phone number to a hunt group. The table contains entries that specify
the following information:

• Telephone number

• The hunt group the phone number maps to.

• The minimum number of digits to collect before the ATPM starting address lookup.

• The maximum number of digits the ATPM collects before it considers the dial string is

complete.

• Number of digits forward to the destination.
Address table sample:

Address Entry Hunt Grp_Id Min. Digits Max. Digits

200 1 3 3 0 None
201 3 3 3 0 None
899 11 3 3 0 None

---------------------------------------------------------------------------­ 1 2 1 1
3 2 1 2
5 2 1 4
11 2 1 11

Destination Table

The destination table maps a destination to a telephony port or the IP address of a remote VIP.
Destination table sample

Dest id Mode Destination

------------------------------------------------------­ 1 Local PORT = 0
3 Local PORT = 2
5 Local PORT = 4
11 H.323 Dest = 192.168.0.55/1720 TCP
12 DNS Dest = planetvip.dyndns.org /1720 TCP

3.6 DTMF Relay

Voice from PSTN is compressed by VIP before sending across the IP network and then decom­pressed by the destination VIP. The voice coders supported by VIP are designed for ideally com­pressing and decompressing human voice. If the compression / decompression process is per­formed on DTMF tone which needs to be conveyed across IP network, distortion might be too sig­nificant to be not cognizable in the receiving end. To overcome the shortcoming that the voice cod­ers cannot perfectly encode DTMF tone, VIP encodes DTMF tone into special packets. The pack­ets are then sent to the destination VIP via a separate IP connection. The destination VIP decodes
the packets, generates the DTMF tone, and then sends the tone to the PSTN. The way VIP han­dles DTMF tone is so called DTMF relay.

VIP handles DTMF relay per H.323 specifications. Certain third party VoIP devices may handle
DTMF relay per IMTC standard. For VIP to interoperate with those VoIP devices, users need to
specify which remote VoIP devices uses IMTC conforming DTMF relay technique. Refer to CLI
command set h323 imtc_dtmf {add|del} ip_addr for detailed information on how to select DTMF re­lay mode.

3.7 Voice Codecs

Voice codecs supported by VIP include G.711, G.723.1 5.3kbps, G.723.1 6.3kbps and G.729 AB.
When setting up a call, two VIP automatically negotiate with each other until an agreed upon codec
is determined.
