A.1.2.1 Connecting an SPCI2S to an M34 Block Connector
The following table provides information on connecting an SPCI2S (working as a DTE) to a V.35 block
connector (working as a DCE).
Also, it may be necessary to connect:
• M34 pin E (DCERDY-P/DSR) to M34 pin H (DTERDY-P/DTR) and
• M34 pin C (RTS-S) to pin D (CTS-P)
A.1.2.2 Connecting an SPCI2S to a Nortel DMS100
The following information has also been used in conjunction with a Nortel™ DM100™ (25-pin D-type
connector).
Also, it may be necessary to loopback control signals at the Nortel connector if it is not possible to disable
their function. The Nortel switch must be set to DCE mode.
A.1.2.3 Connecting an SPCI2S to an INET Tester
The following information has been used to connect an SPCI2S to an INET™ tester (Turbo7/Spectra) using a
25-pin D-type connector.
