ASM-40 Ver. 1.0 ASM-40/R with G.703-HDB3 Interface A-5
A.3 ASM-40/R with Ethernet Interface, DTE
Connection
ASM-40/R with the IR-ETH or IR-ETH/QN Ethernet interface module uses a
CIA/ETH interface adapter, which converts one DB-25 connector to an RJ-45
connector. If you intend to prepare a DB-25/RJ-45 adapter cable yourself, refer to
Figure A-1
and
Table A-3
for the pin designations and their assignment.

A.4 ASM-40/R with G.703-HDB3 Interface
ASM-40/R with G.703-HDB3 DTE interface uses the terminal block (line) and
DB-25 (DTE) connectors located on the rear panel of the ASM-MN-214 card cage.
Figure A-2
illustrates the terminal block line connector, and
Table A-4
lists the
DB-25 connector pinout.
When using an unbalanced option, pins marked with an asterisk (*) may be
connected to the signal ground on the PCB.
