Support Telephone Number Call your NEC America, Inc. authorized dealer if you need assistance when installing, programming, or using your system.

Prerequisites for Installation The following items are required before installing the i-Series Gateway.

�� 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 facility

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∅ s allocated ____________ 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 phones to be active simultaneously.

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

your System Administrator’s Guide.

�� If using an asynchronous connection, an ISDN Terminal Adapter (TAs) from the list below must be installed and operational at BOTH the corporate facility and at the Branch Office location. This list is complete as of the release date of this document.


�� Consult the supported TA list for the most commonly used devices.

Note: In order for the Async-RS 232 Dial feature to work properly for these devices, you need to setup each device to accept incoming “AT Commands”. Consult the documentation provided with each device for proper instructions.

�� Proper wiring with adequate punch down blocks to connect the Gateway to the PBX. Must be wired according to Table 3, page 7, and provide RJ-21 female connector.

�ISDN Requirements (for Asynchronous connections) Before you install your units, you need to order an ISDN line at both the local site and the remote branch office. This ISDN line should be capable of the following: �� The ability to make two “data” calls using both B Channel of the ISDN line. �� If Long Distance, both “data” calls need to be routed as a “data” call. Note: Confirm this with your Long Distance provider when you order your ISDN Line.


Information for the System Administrator �Once your ISDN line is installed, you will be provided with two Service Profile Identifiers (SPIDs) and two Directory Numbers (DNs). Provide these numbers to the System Administrator. Note: When installing the ISDN TAs, make sure you write down the SPIDs and DNs. Keep this information in a safe place for reference. If you do not have the SPIDs or DNs, you cannot program the ISDN TAs.

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.) • Properly installed i-Series Gateway unit Pinout Information Table 8.

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 programming. 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 prompt 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. How to access the Setup Wizard through the MI Path: Gateway->Utilities -> Setup Wizard


Telnet Connection

"��#��You can configure the i-Series Gateway using a Telnet session over the existing LAN connection. A maximum of four Telnet connections can exist per unit at one time. IMPORTANT: • You must configure all IP parameters before you can establish a Telnet session to a unit. • The i-Series Gateway must be powered up and online. (See Power-up procedure on page 8.)
