1-4 OSU 300 User Manual 61200663L1-1
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.
