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
61200217L1-1 T3SU 300 User Manual 1-1
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.

Alarm Connector
The alarm connector is a three-posi tion, screw-type terminal block
that is connected to the three contacts of a Form C-type relay on the
main board of the T3SU 300. This relay is activated any time the
T3SU 300 detects an alarm condition on the T3 network interface.

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

For the 1200217L2 product, the AUX port pr ovides a telephone line
(POTS) connection for the internal V.34 modem.
For both versions of the product, the T3SU 300 can be configur ed as
a dial-in host and also as a dial-out-on-TRAP device (meaning that
the unit dials out to a specified host to report error conditions).
