Technical Specifications 
- 2 x Primary serial V.35/X.21/RS232 port to 4Mbps.
- 2 x Secondary serial V.35/X.21/RS232 port to 512kbps.
- All four ports supported by one DB-78 connector
- Card takes only 1 PCI slot to support 4 ports.
- Power: 550mA at +5v, 60Ma at +-12v.
- PCI 32 bit (5v and 64 bit (3.3v) compatible.
- Temperature range: 0 - 45C.

Features added to support Datascope applications
- All modem control lines are monitored.
- Detection of the presence or absence of TX and RX clock signals, and measurement of the clock rates.
- Either monitoring only or simulation (transmit and receive).
- Monitoring or simulation of ATM or HDLC at line speeds above 2Mbps, BSC at line speeds to 128kbps, Asynch to 256kbps, and raw unformatted bit streams to 2Mbps.
- Time stamps with a resolution of 100 microseconds or better to allow accurate sequencing of events. Each character can be individually time stamped.

Jumpers
| Jumper |
Remarks |
| J2, J3, J4, J9 |
To run the ports using RS232 ONLY with internal clocking set Jumpers J2, J3, J4 and J9 to positions 1 - 2. For all other
configurations, including V.35 with internal clocking, leave the jumpers in the factory position of 3 - 4. |
| J5,J6,J8,J7 |
Change only for use on embedded clock multipoint RS485
applications. |
| J11 |
Factory use only. Do not change |
Cables
The S5142A card is shipped with your choice of mating cables supporting the Primary (4Mbps) port only. These are:
608 |
DB25 - V.35, 1.25M shielded |
|
613 |
DB25 - X.21, 1.25M shielded |
|
607 |
DB25 Straight cable for RS232, 1.25M shielded |
|
Typical Applications:
The S5142 is used to save PCI slots and cost in applications that require more port density than the dual port S5141 card. Functionally, the S5141 and S5142 cards are identical.
1. S5142 Cards and APIs provide X.25 links for ATM hub switch
Sangoma S5142 cards are used for providing multiple WAN links for ATM concentrator hubs. This usually involves protocol conversion and encapsulation, for example:
TCP/IP BSC X.25 Frame Relay
2. S5142 card used as basis of dual line monitor
The S5142 is used to monitor two lines at once without sacrificing extra PCI slots.
