Introduction
to serial line connecting
We supply the following serial port cards:
1. V.28/V.35 double sync/async serial port card WIC-2T
2.
V.28/V.35 single sync/async serial port card WIC-1T
3.
Double differentiated serial port card WIC-2T-V11
4.
Single differentiated serial port card WIC-1T-V11
The
serial port cards can be used on slot1/slot2 of 1750/2620 router,slot1 of 2621
router,slot1/slot3 of 2630 router and slot1/slot4 of 2650 router.Check the
following cases before using the serial port card:
1. The
equipments connected is DTE or DCE.
2. The
connector is hole or pin joint.
3. The
signal standard of the interface
chosed:V.28(EIA/TIA-232),V.35,V.36(EIA/TIA-449),X.21,EIA-530。
The equipment connected to the serial port card should be DTE or DCE. One DCE equipment supplies one clock signal to make the equipment and the router communicate at the same time , but the DTE equipment does not supply clock signal.DTEequipment always connects to DCE equipment.Please refer the file to confirm the the equipment is DTE or DCE. Please refer to the following table if you are not clear about the type of the equipment and the connector assembly :

Interface
standard of the serial port card
The physical protocol supported by the serial port includs:V.24/V.28(EIA/TIA-232),V.36(EIA/TIA-449),X.21,V.35,EIA-530. WIC-2T&WIC-1T only support V.24/V.28(EIA/TIA-232),V.35;WIC-2T-V11&WIC-1T-V11 only support V.36(EIA/TIA-449),X.21,EIA-530. The user can choose ralervent interface cable to connect the special equipment.
Distance
restriction of serial line connecting
The serial port has distance restriction
of communication at any rate and the lower the rate ,the further the
distance.All serial port signals have distance restriction and the signal is
weaken even lost when the distance acesses the restriction.The following table
shows the rate and distance restriction of the different interface:

V.28/V.35
Sync/async serial port card & cable
V.28/V.35 sync/async uses
60-pinsocket and DB60 interface.One DB60 interface supports two sync/async
serial ports(single serial port card uses the first group data).
The definition of serial port DB60 footnote
