Chapter 1 Introduction

PRODUCT OVERVIEW

The T3SU 300 is a multiport DSU/CSU (data servi ce unit/channel service unit) that provides access to T3 services. The unit pr ovides a cost-effective, versatile approach for migrating T1 services to T3. The TDM (time division multiplexer) multiport design allows you to share the cost of a T3 line between multiple applications. This unit maximizes the use of T3 services, providing up to four data ports capable of transmitting and receiving high-capacity, real time data.

A HSSI (high speed serial interface) port is built in along with three slots which accept additional HSSI or V.35 interface cards. The HSSI interfaces support rates between 75 kbps and 44.2 Mbps in 75 kbps increments. The high speed V.35 interface option supports rates up to 10 Mbps in increments of 75 kbps .

Embedded SNMP (simple network management protocol) and TELNET are available through either a SLIP/PPP or a 10baseT ethernet port. Through the Management Information Base II(MIB II), RFC 1407 standards, and an ADTRAN enterprise MIB, the T3SU 300 can be configured, monitored, and diagnosed using standard SNMP network management programs such as Hewlett Packard’s HP OpenView™, IBM’s Netview™, and Cabletron’s Spectrum™.

Complete configuration, diagnostics, and performance monitoring are available through SNMP, TELNET, or a VT 100 terminal interface. This connection can be made via ethernet, a local EIA-232

Chapter 1. Introduction

link, or through the built-in V.34 modem (1200217L2 only). Advanced dial-out on trap capabilities through the built-in modem allow the T3SU 300 t o co ntact r emo te ho sts and al ert them to DS X-3 network conditions (without dedicated management connections). The T3SU 300 is designed for either desktop use or installation in a 19-inch rack.

The major features or the T3SU 300 are as follows:

• Full feature multiport T3 DSU/CSU

• Maximum of four user data ports (HSSI or high speed V.35) available

• Automatic or manual remote configuration

• Embedded SNMP and TELNET management through 10baseT ethernet or SLIP/PPP

• Detailed performance monitoring for local and remote unit s

• Simplified configuration through detailed VT 100 terminal menu structure

• Optional integrated V.34 modem for dial-up and dial-out access (product version 1200212L2 only)

• Standard 5-year warranty

T3 OVERVIEW

T3 provides the same bandwidth as 28 T1s and is used to interconnect high-speed bridges, routers, fr ont-end pr ocessors, a nd data terminal equipment (DTE). T3 service plays a major role in Internet backbones and public organizations needing broad bandwidth for WAN (wide area network) connectivity.

SNMP

The T3SU 300's embedded SNMP feature allows the unit to be accessed and controlled by a network manager through either the auxiliary (AUX) control port or the 10baseT local area network

1-2 T3SU 300 User Manual 61200217L1-1

Chapter 1. Introduction

(LAN) port. The T3SU 300 supports th e M IB-II stan dard, RFC 1213, and the ADTRAN Enterprise Specific MIB.

MIB files are available from ADTRAN in the support section of the ADTRAN Web page at www.adtran.com.

The term SNMP broadly refers to the message protocols used to exchange information between the network m anagement system (NMS) and the managed devices, as well as to the structure of device management databases. SNMP has three basic components:

Network Manager

Control programs that collect, contr ol, and present data pertinent to the operation of the network devices. These program s reside on a network management station.

Agent

Control program that resides in every network device. This program responds to queries and commands from the network manager, returns requested information or invokes configuration changes initiated by the manager, and sends unsolicited traps to the manager.

MIB

Industry standard presentation of all status and configuration parameters supported by a network device.

TELNET

TELNET provides a password-protected, remote login facility to the T3SU 300 that allows a remote user to control the T3SU 300 through the terminal menus. Only one TELNET session may be active at a time.

Chapter 1. Introduction

INTERFACE OPTION CARDS

Optional interface cards may be purchas ed to equip the T3SU 300 with up to three additional ports. Both HSSI and V.35 interface cards are available.

HSSI Card

The optional HSSI card plugs into one of the three card slots on the rear of the T3SU 300. With optional HSSI cards instal led, the total

44.2 Mbps bandwidth of the T3 can be divi ded among the total

number of ports to provide multiple data channels over the T3. The total bandwidth of the T3 can be divided among the available ports in any fashion, as long as the divisions are on 75 kbps boundaries.

The HSSI card can be hot inserted or swapped. When it is inserted in a slot on the rear panel and its faceplate is secured to the rear panel of the T3SU 300 with the integral thumb screws, a PCMCIA type connector on the card mates with a compatible connector on the main board of the T3SU 300. A standard 50-pin HSSI connector is then available for DTE connections. See the section DTE Port Interface Card Slots on page 2-4 for more information on installing option cards.

V.35 Card

The optional V.35 card plugs into the card slots on the rear of the T3SU 300 to provide a V.35-type DTE interface. Operation of the V.35 card is similar to that of the HSSI card except that the maximum bandwidth of the V.35 card is limited to 10 Mbps.

Like the HSSI card, the V.35 card can be hot inserted or s wapped, and it installs just as the HSSI card does. Instead of the standard HSSI connector, this card contains a standar d 34- pin V.35 connector for DTE connections. See the section DTE Port Interface Card Slots on page 2-4 for more information on installing option cards.

DTE Port 1 (HSSI Interface)

DTE port 1 is a built-in HSSI port that resides on the main board of the T3SU 300. The bandwidth of this port is configurable from 75 kbps to 44.2 Mbps in 75 kbps increments. When a single application requires the full 44.2 Mbps of bandwidth, the T3SU 300 does not have to be equipped with additional port cards.

Auxiliary Port

The auxiliary (AUX) port is an 8-pin modular jack located on the rear panel of the T3SU 300. The function of this port differs, depending on which version of the T3SU 300 you have (1200217L1 or 1200217L2).

For the 1200217L1 product, this port provides a DTE-type, EIA-232 asynchronous serial port. This port can be connected to a VT 100 terminal or to a device running SLIP or async PPP. This port can also connect to an external modem to provide dialup VT 100, SLIP, or PPP. This port’s mode and baud rate are selected in the

POINT-TO-POINT MULTIPORT APPLICATION

When networking requirements call for sharing the bandwidth of a point-to-point T3 circuit, additional data ports can be installed into the T3SU 300 for multiport operation. The T3SU 300 supports up to three port option cards (either high-speed V.35 or HSSI). These option cards are hot swappable and can be field installed. See the section DTE Port Interface Card Slots on page 2-4 for more information on card installation.

This application (shown in Figure 7-2) supports two subnet connections via two different routers, a video conferencing connection, and a main frame data connection. The T3SU 300 supports the high speed data connection requirements of the routers (using the HSSI ports), as well as the V.35 data connection requirements of the video conferencing unit and the main frame. The bandwidth is split by the T3SU 300 to provide 18 Mbps for each router, 1.5 Mbps for the video conference units, and 6 Mbps for the main frames.

In this application example (shown in Figure 7-3), a carrier provides fractional T3 access at 8 Mbps for internet connectivity. The data connection can be either V.35 or HSSI at either location. This network uses a HSSI port at the carrier’s internet POP (point of presence) and a high-speed V.35 connection at the customer’s router. The carrier manages both the local and remote T3SU 300s via SNMP. Ta ble 7 -3 gives an example configuration for this application.

While in DTE Loopback, data from the host is transmitted into the network.

REMOTE SNMP MANAGEMENT APPLICATION

A remote T3SU 300 can be managed by a local management station if the remote unit is assigned its own IP addr ess. Th is address must be assigned at both the near and far ends. Also, the option must be enabled on both units.

In this application example (shown in Figure 7-4) a local T3SU 300, connected to the same LAN as the management station, provides management access to a remote T3SU 300. The lo cal unit has the remote unit’s IP address in its
