Safety Precautions

This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicabl es aux appareils numériques (de la class A) prescrites dans le Règlement sur le brouill age radi oélect riq ue éd icté par le mi nist ère des Communi ca tion s du Canada.

The Industry Canada label indentifies CS-03 certified equipment. This certification means that the equipment meets certain telecommunications network protective, operational and safety requirements. Industry Canada does not guarantee the equipment will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single line individual service may be extended by means of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.

Repairs to certifi ed equipmen t should be made by a n authoriz ed Canad ian maint enance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.

This equipment is intended to be installed only in a Restricted Access Location that meets the following criteria:

• Access can only be gained by service personnel or users who have been instructed about the reasons for the restrictions applied to the location and about any precautions that must be taken.

• Access can only be gained through the use of a lock and key or other means of security, and is controlled by the authority responsible for the location.

When handling this equipment, follow these basic safety precautions to reduce the risk of electric shock an d in ju ry :

• Follow all warnings and instructions marked on the product and in the manual.

• Unplug the hardware from the wall outlet before cleaning. Do not use liquid

cleaners or aerosol cleaners. Use a cloth slightly dampened with water.

• Do not place this product on an unstable cart, stand, or table. It may fall, causing serious damage to the product.

• Slots and openings in the shelves are provided for ventilation to protect them from overheating. These openings must not be blocked or covered. Never place this product near a radiator or heat register.

Verilink DIU 2131 User Manual

High-Low Application

This user manual describes the DI U 2131 High-Low module within Verilink’s Access System 2000 (AS2000) platform. This module operates in conjunction with a CSU—either an SCC 2020, TAC 2010 or DIDCSU 2912—to multiplex a high-speed and low-speed application onto a single T1. The latest firmware revisions, SCC

2.06 and TAC 1.6, enable the user to configure all of the modules at the far end node, not just the controller. Passwords are used to control access between the near and far ends.

NOTE:

The High-Low module multiplexes up to 24 channels from two synchronous ports—one high-speed for aggregating multiple data channels and one low-speed for subrate data—and transfers the information onto a single T1 line.

This manual requires familiarity with standard telecommunica tions te rminol ogy, appl icat ions, an d practi ces.

There are two data ports on the DIU 2131 rear c onnector module, the HLM 2532:

•

Port 1 is a high-sp eed V.35 synchro nous port , pr oviding n × 56 (default) or n × 64 kbit/s of bandwidth .

•

Port 2 is a low-speed RS-232 synchronous port using a single DS0, providing spee ds of 2.4, 4.8, 9.6, 19.2, 28.8, 38.4, 56, or 64 kbit/s.

The front modules and their rear connector modules are shown in the figures below.

The DIU 2131 can be in a node controlled by an SCC or NCM controller module. These controllers can be managed by the Craft interface, SNMP or Node Man ager. Remotely located users can also use Telnet over Ethernet or SLIP to access the Craft interface. See the user manual for the controller in your node.

Sample Application

Quick Set-up

The DIU 2131 multiplexes data from a high-speed and low-speed application onto a shared T1 l ine. The high-speed appli cation could be a file server, router, bridge, video teleconference codec, or any device with a synchronous connection. The low-speed application can be up to 64 kbit/s, or one T1 timeslot. A typical application is an automatic teller machine.

This chapter describes all of the steps required to set up the DIU 2131 for a typical appl ication. Your settin g s may be different, for example the number of timeslots needed for your high-speed application.

Refer to the appropriate controller module and management software user manua l s for more detailed information. This chapter focuses on the DIU 2131 config uration.

The DIU 2131 is ideally suited to provide connectivity between branch offices and data processing hubs within the banking industry.

Physical Configuration

The following steps are required at both ends of the point-to-point connection before config uring the firmware.

DS0 1 is for a low-speed teller application connected to the Port 2, RS-232 connecto r.

DS0s 2-5 are for a 220 kbi t/s router connected to the Port 1, V.35 connector.

The T1 has ESF framing and B8ZS line coding. The DIU 2131 is sending data t o the T1 port o n an SCC 2020 in

a Dual-line shelf. We are accessing the DIU 2131 via a terminal emulator

connected to the Craft por t o n the SCC 2020. The information is passing to the SCC 2020 using Data Bus A

Performance

DIU 2131 Front Panel

The DIU 2131 front panel has three LEDs for each customer data port:

Near End Loop LED

Far End Loop LED

STAT LED

The Near End Loop LED lights yellow when t he associa ted d ata po rt is looped on the DIU.

The Far End Loop LED lights yellow when th e associated data port is looped at the far-end DIU. This occurs only if the loop-up command was sent by the near-end DIU to the far-end DIU over the T1 circuit.

The STAT (DIU 2131 status) LED is a tri-color indicator which shows one of the following conditions for each data port:
