Prerequisites for Installation

The following items are required before installing the i-Series Gate wa y.

1HWZRUN5HTXLUHPHQWV



Appropriate network terminating device must be installed, configured, and functioning at both the corporate facility and the branch office and both must support an RS-232, V.35 or V.530 synchronous, asynchronous or Voice over IP interface.



A 50-pin cable with an RJ-21 female connector.



Appropriate network terminating device must be installed and functioning at both the corporate facilit y and the branch office.



The data connection between the corporate facility and the branch office MUST be operational and configured properly.



The system has been designed to operate from 100-240 VAC, 50-60Hz. Power should not be applied to the i-Series Gateway unit until specified in the installation procedures.



The Gateway’s power supply and cabling should be installed away from high power/high RF noise devices such as computers, fans, fluorescent ballast, power supplies, etc.



Use good wiring practices. Do not run wires over fluorescent lights, computers, air conditioners, etc. as this can introduce noise to the modems.



The distance from the PBX to the i-Series Gateway should not exceed 500 feet.



Obtain the following information from your customer:

MODE: (V.35, RS-232, RS-530)_________________ NUMBER OF DS 56K or 64K_______________

number of DS

∅s X 64 or 56K(above) = _________ SYNC RATE ÷ number of stations = _______

If the result is at least 40 KBPS use ADPCM32 voice compression If the result is less than 40 KBPS but at least 32 KBPS use ADPCM24 voice compression If the result is less than 32 KBPS but at least 16 KBPS use G.729A voice compression If the result is less than 16 KBPS, there is not enough bandwidth for all phone s to be active simultaneously.

Note: This is a general guideline for calculating bandwidth requirements. For more information, see

your System Administrator’s Guide.



Dial-Up Management Console

Introduction

The MI includes Zmodem functionality for the DB-9 dial-up management console port. An external modem attached to the DB-9 port (not included with unit) is required to dial into the i-Series Gateway management console interface. This console interface allows remote dial-up access using Zmodem protocol to the management console. (Refer to Appendix A.)

When a dial-up connection is established to the MI of one unit, it is possible to “Rlogin” to other connected units to access the MI of those units when the network connection between units is not functioning. This connection allows access to all features and functions of the MI and the ability to configure, monitor, and troubleshoot the unit from a remote location. (See the figure on page 6.)

Required Equipment

• Modem (not included with unit)

• Direct analog telephone line for connection to the modem

• RS-232, DB-25 to DB-9 modem cable [male-male] (See Table 8, below, for pinout information.)

• P r oper ly installed i-Series Gateway unit

Setup Wizard

The i-Series Gateway provides a console setup wizard that guides a user through most of the required programming/configuration required to complete initial setup of the units, via the VT100 management console accessed through the DB-9 management port. You can use the MI to set parameters not configurable through the wizard.

Access the setup wizard through the console MI, requiring a PC to connect to the unit (i-Series Gateway) via the DB-9 console port. The wizard queries the user on the basics of the particular configuration, and uses this information to establish the initial configuration pro gramming.

Standard Console UI vs. the Setup Wizard

When a unit is first powered up, it checks a Setup Wizard flag. If the flag is set, the standard console UI is displayed. If the flag is not set, the system asks you to run the Setup Wizard. After this initial p rompt the Setup Wizard flag is set. This prevents the unit from asking you to run the Wizard again. You can also access the Setup Wizard through the console MI if you want to run it later.
