Jumpers

| Jumper | Remarks |
| J2, J3, J7, J8 | To run the ports using RS232 with internal clocking set Jumpers J2, J3, J7 and J8 to positions 1 - 2. For all other configurations, including V.35 with internal clocking, leave the jumpers in the factory position of 3 - 4. |
| J4, J5 | Change only for use on embedded clock multipoint RS485 applications. |
| J11 | Factory use only. Do not change |

Cables
The S5141 card is normally shipped with your choice of cables supporting the Primary (4Mbps) port only. These are:
| 617 | DB37 - V.35, 1.25M shielded |
|
| 618 | DB37 - X.21, .25M shielded |
|
| 619 | DB37 - RS232, .25M shielded |
|
For applications that make use of both Primary (4Mbps) and Secondary (512kbps) ports, the 621 dual port upgrade kit substitutes a Y cable and pair of serial cables for the original Primary port cable.
Shown below is the 621kit for V.35, substituting a 620 Y cable plus two 608 V.35 cables for the 617 Primary port cable normally supplied.

Typical Applications
1. S5141 Cards and APIs provide X.25 links for ATM hub switch
Sangoma cards are used for providing the WAN links for ATM concentrator hubs. This usually involves protocol conversion and encapsulation, for example:
TCP/IP BSC X.25 Frame Relay

2. WANPIPET WAN router replacement using S5141 card:

To Replace

3. S5141 card used as basis of Datascope

4. S5141 used for broadcast satellite feed

5. S5141 used for SNA connection using Microsoft's Host Integration Server
