The ADTRAN T3SU 300 is a T3 DSU/CSU capable of providing
users up to four DTE data ports.
This multiport DSU/CSU
provides access to non-channelized T3 services and allows
users to share the cost of a T3 line between multiple
applications. The new, affordable T3SU 300 is the first in a
series of broadband access products from ADTRAN. The T3SU 300
has one HSSI (High Speed Serial Interface) port built into the
chassis.
Expansion slots for up to three additional DTE interfaces
accept optional field-upgradeable interface cards. The cards
can be either HSSI, high-speed V.35, or DSX-1. The HSSI ports
support rates from 75 kbps to 44.2 Mbps, while the high-speed
V.35 ports support rates from 75 kbps to 10 Mbps; both in 75
kbps increments. Each DSX module has 4 DSX-1 interfaces and up
to 3 DSX-1 modules can be supported in a chassis. The T3SU 300
offers complete configuration, diagnostic, and performance
monitoring through a VT100 terminal, SNMP, or Telnet. A series
of front panel LEDs indicate the status of the network
connection, along with the state of each of the four DTE
ports. SNMP traps notify SNMP management platforms of alarm
conditions. External alarm contacts provide connection to a
visual or audible alarm. The T3SU 300 includes VT100 terminal
interfaces on both front and rear panels.
Inband access to a remote unit across the T3 circuit can be
performed manually by the user, or automatically by the host
T3SU 300 unit. For customers needing out-of-band management,
the T3SU has an integrated modem. Time-of-day automatic
reconfiguration allows customers to assign or reallocate
bandwidth to applications based on the time of day, ensuring
that the broadband circuit is always optimized.
Embedded SNMP and Telnet are available through either the
10baseT Ethernet port or the SLIP/PPP port. The T3SU 300 can
be configured, monitored, and diagnosed using standard SNMP
network management programs, such as Hewlett Packard’s
OpenView, IBM’s NetView, and Cabletron’s Spectrum. ADTRAN’s
ADVISION, a GUI interface for HP OpenView, can be used to
manage the T3SU 300, as well as other ADTRAN SNMP products.
The T3SU 300 is also supported by ADTRAN’s N-Form Network
Management Software Suite.
