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 one static IP address to as-

sign VIP.

2.2 Installing VIP

VIP can be used in a desktop configuration. 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 Connecting to the telephony devices

VIP-050 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-450 equips two FXO and two FXS interfaces to

have the great flexibility of PBX connection (FXO), and telephone or FAX machine connection

(FXS).

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.

Warning: connection of incorrect telephony devices to the ports on the TIM can cause permanent

damage to the TIM and/or VIP.

2.4 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.

2.5 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.

2.6 Assigning IP address to VIP

The IP address is the unique logical address identifying each IP node, such as VIP, on an IP net-

work. An IP address is a 32-bit number expressed as four decimal numbers from 0 to 255 sepa-

rated 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 net-

work. 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 config-

uring the gateway. Procedures for assigning IP address, default gateway and subnet mask is avail-

able in Chapter 4.

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:

Capture of telephone number presented as DTMF tones.

Mapping the telephone number to the IP address of remote VIP.

Setting up calls with remote VIPs utilizing SIP call control protocol.

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 re-

ceived 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 ter-

minals 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.

VIP User’s Manual

3.4 Hunt Group

Instead of directly mapping a phone number to a destination, the ATPM first maps the phone num-

ber 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.

3.6 DTMF Relay

Voice from PSTN is compressed by VIP before sending across the IP network and then decom-

pressed by the destination VIP. The voice coders supported by VIP are designed for ideally com-

pressing and decompressing human voice. If the compression / decompression process is per-

formed on DTMF tone which needs to be conveyed across IP network, distortion might be too sig-

nificant to be not cognizable in the receiving end. To overcome the shortcoming that the voice cod-

ers cannot perfectly encode DTMF tone, VIP encodes DTMF tone into special packets. The pack-

ets 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 han-

dles DTMF tone is so called DTMF relay.

VIP handles DTMF relay per SIP 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

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.

2. If the power adapter or power cord is connected to the gateway, check that the cord is securely

plugged into the power socket on the rear of the console.

3. Check that the other end of the power adapter or power cord is securely plugged into the power

outlet.

4. If both ends of the power cord are properly connected and there is still no power, the gateway

might have a faulty power outlet, power adapter, or power cord.

5. Change to another power outlet or obtain another power adapter or power cord.

Chapter 6 Command Line Interface

VIP has a built-in command line interpreter and provides users a Command Line Interface (CLI).

You can configure VIP by entering commands from the CLI.

You can access the CLI from a VT-100 terminal or terminal emulator connected to the RS-232 port

on the front panel or through a Telnet session.

6.1 Connection through Serial Port

The serial port of VIP is fixed at the following settings:

Baud rate

Number of data bit

Parity check

19,200

None

Number of stop bit

Flow control

None

To access VIP through the RS-232 serial port, follow the steps below:

1. Insert one end of the serial cable that came with VIP into the 9-pin RS-232 port (labeled User

Console) on the front panel.

Insert the other end of the cable into your terminal’s serial port.

3. Configure the terminal so that settings for baud rate, number of data bit, parity check, number

of stop bit and flow control capability exactly match VIP’s serial interface. (Refer to you terminal

documentation for more information about setting up these features).

4. Press <Return> from the terminal.

5. VIP displays the following prompts on the terminal and you are ready to access the CLI then.

EVIP>

On most cases, if you enter a command using the wrong number of arguments or inappropriate ar-

guments, the CLI will give further usage.

6.4 Designating IP Address

Some commands require an IP address, which must be designated in a standard format. The IP

address format is 32 bits, written as four octets separated by periods (dotted decimal format) that

are made up of a network section, an optional subnet section, and a host section, as shown in the

following example:

192.168.0.1

6.5 Designating Port Number

Some commands require a telephony port number. VIP designates the first port telephony interface

as port number 0, the 2^ndport as port number 1 and so on.

VIP User’s Manual

6.9 Configuration Management Commands

The configuration management commands allow the user to set values for system configuration pa-

rameters. In addition, it provides mechanisms to allow a user to control when new parameter val-

ues are put in use.

The CLI maintains three areas where the parameters are stored:

Ÿ Temporary

Ÿ Active

Ÿ Non-volatile Storage (NVS)

When a set command is entered and processed, it changes the parameter value in the Temporary

area. This does not affect current operation of VIP, which is using the values in the Active area.

The config activate command moves configuration data from the Temporary area to the Active

area, where it can actually be used. Thus a user can make multiple changes in the Temporary

area using set commands, then put them into use with a single config activate command. (Note

that the config activate command may only be used between calls, and will usually tear down any

in-progress calls when invoked.)

Configuration data in the Active area is only available while VIP remains in operation. If VIP is re-

set, the Active area is reloaded from the data stored in NVS. Data in the Active area may be saved

to NVS by entering the config store command.

For most of the SIP parameter, settings won’t take effect until VIP reset. To ensure the SIP setting

to take effect, it is recommended to reset VIP after changing the settings using the set command.

In summary:

Use set commands to make configuration parameters changes in the Temporary area

Use the config activate command to move the new values into the Active area, available for

use

Use the config store command to save the new Active values in NVS

Reset VIP after changing SIP settings and storing the setting to NVS.

config {activate|store|erase}

Use the activate command to manage the configuration data. A sequence of set command is typi-

cally preceded by and/or followed by the config command for the set command to become active.

Syntax description

Move the configuration from temporary area to active area.

Store the active configuration data into non-volatile storage.

Erase the configuration from non-volatile storage.

set coding profile_id cp_tone_detect {on | off}

This command is used to specify a secondary level of control of call progress tone detection. If the

call progress detection control for a telephony port is set to "As per coding profile" (refer to com-

mand “set port port cp_tone_det_ctrl”), this parameter determines if detection is to be enabled or

not.

Syntax description

Enable call progress tone detection.

Disable call progress tone detection.

set coding profile_id fax_tone_detect {on | off}

This command is used to specify a secondary level of control of V.21 fax tone detection. If the fax

tone detection control for a telephony port is set to "As per coding profile" (refer to command “set

port port fax_tone_det_ctrl”), this parameter determines if detection is to be enabled or not. For a

voice coder, fax tone detection has to be enabled, otherwise, telephony port never switches to fax

mode while the voice coder is active. For a fax profile it does not matter if the fax tone detection is

enabled or disabled.

max_delay

Voice packets from network may have traversed variable path and each packets have experienced dif-

ferent propagation delay. To ease this phenomenon, VIP has a built-in voice packet buffer, which

stores voice packets received from the network. The effect of non-uniform delay among packets is

known as jitter. The voice buffer allows VIP to remove the packet jitter from the incoming packet

stream before decompressing and sending the packet to telephony port for playing out. This command

is used to set the size of voice buffer.

Chapter 7 Upgrading and resetting VIP

VIP-450 is able to have system functionality enhancement via software upgrade. This must be oper-

ated in upgrade mode. In firmware upgrade mode, limited commands allow users to read new revision

codes from a remote TFTP server and write into the built-in flash non-volatile storage.

To enter download mode, either Telnet or Console (RS-232) connection can take the job, and a TFTP

server is required by VIP to complete firmware upgrade process.

7.1 Firmware upgrade

To switch from normal operation mode to download mode, use the download CLI command.

ITG> download <Enter>

Note: To be able to switch to download mode from Telnet session, TFTP loader on VIP must be ver-

sion 3.00 or higher. To upgrade to firmware version 3.03 or above, bootloader version 4.01 or

above is required.

After download command is inserted, VIP will terminate all on-going calls, reset and enter firmware

download mode. If you enter download mode from Telnet session. The Telnet session will be termi-

nated too. You need to re-connect to VIP from Telnet client to be able to access the firmware download

mode.

Before going any further, please note: NEVER, NEVER TURN OFF POWER while firmware up-

grade is working in progress!! (Please ensure power supply is stable before firmware upgrade is

executed.)

TFTP server is required to complete VIP series firmware upgrade process; there are various TFTP

server software on the market, please utilize the existing software or find a new one on the net to com-

plete upgrade process. (In this chapter, 3CDeamon TFTP server was installed for demonstration.)

TCP/IP Configuration:

Computer installed with TFTP server: 192.168.0.7

VIP: 192.168.0.1

Note: If a Telnet connection is built behind NAT environment, TCP port 69 MUST be reserved for data

communication.

1. Execute TFTP server program, assign firmware file location, and save the path if necessary. (In this

sample datagram, the file is assigned in c:\) (This part might vary on different kind of TFTP server.)

2. Allocate VIP firmware file in the directory, and apply the modification (if required).

Note: TCP port 69 is required for TFTP access.

VIP configuration:

Telnet session

a) Under Telnet firmware download mode, the user name: eitg; password: 123 (password may

vary because of user’s configuration) is used for logging on VIP

b) Under ITG> prompt, insert command: download to enter VIP firmware upgrade mode.

c) Insert command: “start” and answer questions on screen to proceed firmware upgrade.

d) When VIP prompts downloading firmware file into EEPROM, insert “y” to continue.

e) Wait till firmware is fully loaded into VIP, insert “quit” to leave firmware upgrade mode and an-

swer “y“ to reboot machine when VIP prompts for restart.
