10 T1 / E1 Interface Connections
The back panel of Sleipnir-1-PCI contains ether a RJ45 connector or two BNC
connectors. The RJ45 connector provides balanced 100 / 120 ohm transmit and receive
connection, while the BNC connectors provide unbalanced 75 ohm connections.

11 Clocks
On the Sleipnir-1-PCI board, all the internal TDM data highways and the all the devices
processing TDM data are synchronized to one clock reference. The clock reference can
be derived from multiple sources and then routed to all the devices. The following clock-
ing sources are supported by Sleipnir-1-PCI:
•
Clock extracted from the incoming T1/E1/J1 span
•
External 2.048 kHz clock (J3 connector)
•
On-board free running oscillator
The J2 connector can be used to output the Sleipnir-1-PCI clock reference to another
device or equipment.
12 JTAG
The JTAG port (reference designator J1) are used for Board Testing, programming of
The FPGA PROMS, and Connecting the DSP emulator board for DSP Software
Development.
