1-4 T3SU 300 User Manual 61200217L1-1
INTERFACE OPTION CARDS
Optional interface cards may be purchased 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 installed, the total
44.2 Mbps bandwidth of the T3 can be divided 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 swapped,
and it installs just as the HSSI card does. Instead of the standard
HSSI connector, this card contains a standard 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.
