Introduction

PRODUCT OVERVIEW

The OSU 300 is a multiport DSU/CSU (data service unit/channel service unit) that provides access to high-speed services over single-mode or multi-mode fiber. The unit provides a cost-effective, versatile approach for delivering high-speed frame relay and dedicated digital services at data rates from 75.18 kbps to

44.2 Mbps. The TDM (time division multiplexer) multiport design allows you to share the cost of the fiber link between multiple applications. This unit maximize s the use of high-speed services, providing up to four data ports capable of transmitting and receiving high-capacity, realtime data.

The OSU 300 contains a built-in HSSI (high speed serial interface) port and three expansion slots which accept additional HSSI, V.35, or Quad DSX-1 interface cards. The HSSI interfaces support rates between 75 kbps and 44.2 Mbps in 75-kbps increments. The highspeed V.35 interface option card supports rates up to 10 Mbps in increments of 75 kbps. The Quad DSX-1 interface card provides four DSX-1 lines. Each DSX-1 port supports rates up to 1.544 Mbps.

Embedded SNMP (simple network management protocol) and Telnet are available through either a SLIP/PPP or a 10BaseT Ethernet port. Through the Management Information Bas e II (MIB II), and RFC 1213 and 1407 standards, and an ADTRAN Enterprise MIB, the OSU 300 can be configured, monitored, and diagnosed using standard SNMP network management programs such as Hewlett Packard’s HP OpenView™, IBM’s Netview™, Cabletron’s Spectrum™, and MACS.

61200663L1-1 OSU 300 User Manual 1-1

Chapter 1. Introduction

Complete configuration, diagnostics, an d performance monit or ing are available through SNMP, Telnet, or a VT-100 terminal interface. This connection can be made via Ethernet or a local EIA-232 link. The OSU 300 is designed for either desktop use or for installation in a 19-inch rack.

The major features of the OSU 300 are as follows:

• Full feature multiport optical DS3 DSU/CSU

• Maximum of four user data ports: one integrated HSSI port and three additional slots for optional HSSI, high-speed V.35, or Quad DSX-1 cards

• Automatic or manual remote configuration

• Embedded SNMP and Telnet management through 10BaseT Ethernet or SLIP/PPP

• Detailed performance monitoring for local and remote units

• Simplified configuration throug h d etailed VT-100 terminal menu structure

OPTICAL INTERFACE PORT

• The optical interface of the OSU 300 consists of either a singlemode or a multi-mode transceiver module comprised of a transmitter, a receiver, and an SC or ST rec eptacle.

• The optical interface port supports angled SC type optical connectors (1200663L1 and L2 only).

• The optical interface port operates in the 1280 nm to 1335 nm wavelength range (1 310 nm nominal).

• The total output power is 8 mW, as defined by IEC with a 50 mm ap erture at 10 cm di stance.

• The optical interface uses two fibers, one for each direction of transmission.

• The transceiver optical budgets for the optical transceivers are 28dB (single-mode) and 9 dB (multi-mode). See the Optical Interface Port se ction on page 2-7 for calculations .

• The optical interface complies with the physical interface parameters listed in ITU-T recommendation G 957.

SNMP

Chapter 1. Introduction

• The IEC Class 1 laser is safety comp liant under normal

operating conditions. The Class 1 rating is due to an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures. The FITS rating of the internal shutdown circuit is less than 500 FI TS.

• The FDA Class 1 laser is saf e ty FDA compliant.

• The product is shipped with a removable process plug

covering the optical interface.

• A mechanical cover engages when the fiber cable is removed

from the optical interface. The cover provides dust protection in the event of the optical interface being disconnected, and additional protection to the human eye.

The OSU 300's embedded SNMP feature allows unit access and control by a network manager through either the auxiliary (AUX) control port or the 10BaseT local area network (LAN) port. The OSU 300 supports the MIB-II stand ar d, RFC 1213 and 1407, and the ADTRAN Enterprise Specific MIB.

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

Network Manager

Control programs that collect, control, and present data pertinent to the operation of the network devices. These programs 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.

61200663L1-1 OSU 300 User Manual 1-3

Chapter 1. Introduction

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 OSU 300 that allows a remote user to control the OSU 300 through the terminal menus. Only one Telnet session may be active at a time.

INTERFACE OPTION CARDS

Optional HSSI, V.35, or Quad DSX-1 interface cards may be purchased to equip the OSU 300 with up to three additional ports.

HSSI Card

The optional HSSI card plugs into one of the three expansion slots on the rear of the OSU 300. With optional HSSI cards installed, the total 44.2 Mbps bandwidth of the DS3 can be divided among the total number of ports to provide multiple data channels over the DS3. The total bandwidth of the DS3 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. Once the card is inserted into an expansion slot and its faceplate is secured to the rear panel of the OSU 300 with the integral thumb screws, a PCMCIA type connector on the card mates with a compatible connector on the main board of the OSU 300. A standard 50-pin HSSI connector is then available for DTE connections. See the section DTE Ports 2-4 (Expansion Slots) on page 2- 5 for more information on installing option cards.

1-4 OSU 300 User Manual 61200663L1-1

V.35 Card

The optional V.35 card plugs into an expansion slot on the rear of the OSU 300 to provide a V.35-type DTE interface. The V.35 card operates similarly to 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 swapped, and it installs just as the HSSI card does. However, instead of the standard HSSI connector, this card contains a standard 34-pin V.35 connector for DTE connections. See the section DTE Ports 2-4 (Expansion Slots) on page 2-5 for more information on installing option cards.

Quad DSX-1 Card

The optional Quad DSX-1 i nterface car d plugs into the car d slots o n the rear of the OSU 300. This card allows you to transport up to four DSX-1 lines per card over the DS3 interface of the OSU 300 along with high-speed data from the other HSSI/V.35 ports. This configuration allows connect ivity of both voice channels and highspeed data channels for two point-to-point sites using only one network interface. Up to three cards may be installed into the OSU 300 port card slots.

Like the other interface cards, the Quad DSX-1 card can be hot inserted or swapped. See the section DTE Ports 2-4 (Expansion Slots) on page 2-5 for more information on installing option cards.

Even though the Quad DSX-1 interface card allows you to transport T1 information, the OSU 300 still operates the DS3 interface in an unchannelized fashion. Therefore, your DS3 network provider must supply you with an unchannelized, point-to-point DS3.

DTE Port 1 (HSSI Interface)

DTE port 1 is a built-in HSSI port that resides on the main board of the OSU 300. Configure the bandwidth of this port in 75 kbps increments from 75 kbps to 44.2 Mbps. If a single application requires the full 44.2 Mbps of bandwidth, the OSU 300 does not have to be equipped with additional port cards. Appendix A contains the pinout for this port.

Alarm Connector

The alarm connector is a three-position, screw-type terminal block that connects to the three contacts of a Form C-type relay on the main board of the OSU 300. This relay activates any time the OSU 300 detects an alarm condition on t he high-speed network interface. Table 2-1 describes the alarm connector terminal block. Use the A disable the alarm function.

2-6 OSU 300 User Manual 61200663L1-1

Optical Interface Port

The OSU 300 optical interface port consists of a single-mode or multi-mode transceiver module comp osed of a transmitter, a receiver, and an SC or ST receptacle. The optical interface port supports angled SC type optical connectors (61200663L1 and L2 only) and operates in the 1280 nm to 1335 nm wavelength range (1310 nm nominal). The total output po wer is 8 mW with a 50 mm aperture at 10 cm distance, as defined by IEC. The optical interface uses two fibers, one for each direction of transmission.

The transceiver optical power budgets for the optical transceivers are 28dB (single-mode) and 9dB (multi-mode). These budgets are calculated as follows:

Single-Mode

Worst case optical transmit power = -5dBm Worst case optical receiver sensitivity = -34dB m

Calculations: (34 - 5) dB = 29 dB - 1dB (optical path penalty) = 28dB

Chapter 2. Installation and Operation

Multi-Mode

Worst case optical transmit power = -20dBm Worst case optical receiver sensitivity = -30dB m

Calculations: (30 - 20) dB = 10dB - 1dB (optical path penalty) = 9dB

The optical interface complies with the physical interface parameters listed in ITU-T recommendation G 957, with IEC Class 1 laser safety requirements (under normal operating conditions) and with FDA Class 1 laser safety requirements. The OSU 300 contains an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures, thus the Class 1 rating. The FITS rating of the internal shutdown circuit is less than 500 FITS.

61200663L1-1 OSU 300 User Manual 2-7

Chapter 2. Installation and Operation

The OSU 300 comes with a removable process plug that covers the optical interface. A mechanical door engages when th e fiber cable is removed from the optical interface (see also, Figure 2-2 on page 2-4). This door protects the unit from dust in the event of the optical interface being disconnected, and it provides additional protection for the human eye from the laser beam.

POWERING THE UNIT

The OSU 300 can be powered from either a standard AC mains supply or a 48 VDC Supply. When mains powered, the unit receives power via an external power supply that converts the mains power to a usable 4 8 VDC source. When powered by the AC mains supply , the unit operates normally within specification when supplied with AC voltages from 190–264 VAC at 47–53 Hz. The 48 VDC source interfaces to the rear panel of the unit through a screw-down terminal block. A nylon plug allows strain relief on the power cabling to the system.

The chassis should be connected to an earth ground.

The following requirements must be met during installation of the DC version of the OSU 300:

1. The unit must be connected to a reliably grounded -24 or

-48 VDC source which is electrically isolated from the AC

source.

2. The branch circuit overcurrent protection should be a fuse or circuit breaker rated 48 VDC, 15 A.

3. The unit should be installed in accordance with the requirements of NEC NFPA 70.

4. A readily-accessible disconnect device that is suitably approved and rated should be incorporated in the fixed wiring.

Remote Port Payload Loopback

This selection initiates a payload loopback on the remote OSU 300 for all data on the selected port. Perform this test to verify the integrity of the portion of the DS3 link connecting the local DTE and the selected port of the remote OSU 300. All other ports on both the local and remote units are unaffected.

Remote Payload Loopback with BERT

Perform this test to verify the integrity of the link between the selected port of the local OSU 300 and the corresponding remote OSU 300 port. During this test, the remote unit loops back all data for the selected port, while the local unit sends and checks the selected BERT pattern. The loopback point and the signal paths for the remote OSU 300 are the same as the payload loopback test for the local OSU 300 (shown in Figure 6-5 on page 6-5).

Applications

This chapter provides examples of some common T3 applications. The examples include a single port DSU/CSU full T3 bandwidth application, a point-to-point multiport application (page 7-2), a fractional T3 application (page 7-4), a remote SNMP management application ( page 7-6), and a voice application (page 7-7). The configuration selections given in these examples may need modification based on your network configuration.

SINGLE PORT FULL T3 BANDWIDTH

In applications requiring full T3 bandwidth, the OSU 300 operates with other vendor products that support 44.2 Mbps data over unchannelized T3 circuits.

In the application shown in Fi gure 7-1, th e OS U 300 provides network connectivity for a ro uter runnin g at 44. 2 Mbps. The data is frame relay and the unit is SNMP-managed via th e local Ethernet. See Table 7-1 on page 7-2 for an example configuration.

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 OSU 300 for multiport operation. The OSU 300 supports up to three port option cards (Quad DSX-1, V.35 or HSSI). These option cards are hot-swappable and can be field installed. See the section DTE Ports 2-4 (Expansion Slots) on page 2- 5 for m or e inf ormati on on card installation. A configuration example of this application using a Quad DSX-1 card is on page 7-7.

This application (shown in Figure 7-2 on page 7-3) supports two subnet connections via two different routers, a video conferencing connection, and a main frame data connection. The OSU 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.

7-2 OSU 300 User Manual 61200663L1-1

Chapter 7. Applications

The bandwidth is split by the OSU 300 to provide 18 Mbps for each router, 1.5 Mbps for the video conference units, and 6 Mbps for the main frames. See Table 7-2 for an example configuration of this application.

FRACTIONAL T3 CARRIER APPLICATION

When network providers want to provide service at rates less than full T3, OSU 300 units can be used in pairs for deploying s ub- T3 rate services.

In this application example (shown in Figure 7-3 on page 7-5), 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 ca rri e r’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 OSU 300s via SNMP . Table 7-3 on page 7-5 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 OSU 300 can be managed by a local management station if the remote unit is assigned its own IP address. This address must be assigned at both the near and far ends. Also, the D option must be enabled on both units.

In this application example (shown in Figure 7-4) a local OSU 300, connected to the same LAN as the management station, provides management access to a remote OSU 300. The local unit has the remote un it’ s I P a dd r ess in i ts R IP address is entered into the remote unit’s L field. Table 7-4 gives an example configuration for this application.
