remote communication between risc 128 portto 16 port concentrator
aix 3.2.3/trying to do remote communication between risc 128 port
controller to 16 port concentrator
DESC: customer is connecting a single remote RAN to a 128 port
adapter. He is using a T1 line and Paradyne 3164 DSU. This dsu has a
db25 connector that uses EIA-530. What cable does he need to connect
this to the RAN unit?
ACT: He already has the pinouts of the NE, NF cables. These are for
NEXT: customer will fax in the pinout of the db25 connector on his
ACT: talked with customer again, and I was mistaken about the V.35.
The only description he has of the port on the Paradyne is EIA-530,
DB25 port. waiting on fax still.
The customer has a DSU/CSU pair that requires the use of EIA-530
protocol for data transfer. The customer is interested in using these
with the 128 port async adapter. They have a remote site they are
trying to bring on-line.
Unfortunately this type of protocol is unsupported on the 128 port
async adapter. However, I have obtained a copy of the EIA-530 standards
and comparing what EIA-530 requires with what the 128 port adapter
requires the following pinout was constructed: (This pinout has not
been tested, and is unsupported)
