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.
Chapter 1. Introduction
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.

Desktop Installation
Follow these steps when using your OSU 300 as a desktop unit:
1. Affix the four adhesive-backed rubber feet to the bottom of the
unit, one on each of the four corners. The feet should be placed
approximately one inch from the front or back and one inch
from the sides of the unit
2. Make all network, DTE, and power connections to the rear of
the unit. See the section Powering the Unit on page 2-8 for more
information on making the DC power connection.
3. Using the 8-position modular to DB-25 female connector and
the 8-position modular to 8-position modular cable, connect a
VT-100 terminal device to the CONTROL interface jack on the
front panel of the unit.
REVIEWING THE REAR PANEL
The OSU 300 rear panel contains a DC terminal block and provides
a strain relief nylon plug that allows you to tie off the input power
cable, thus relieving strain on the cable. The rear panel also
provides three expansion slots, a built-in HSSI interface, an alarm
output terminal block, a LAN port, an optical interface with sliding
door, and a removable dust cover for the optical interface. Pin
assignments for the connectors are given in Appendix A. Figure 2-1
on page 2-4 shows the OSU 300 rear panel, and Figure 2-2 on page
2-4 shows the movement of the optical int erface door.

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.
