We have a project here to install a PAD connected to the Costa Rican
packet switched service RACSAPAC. We want to identify as quickly as we
can suitable equipment to purchase.
Could you possibly help us to obtain information on:
* Technical specification - the more detailed the better.
* Price
* Delivery
* Information on repair and spares. Will they provide a
service manual and circuit diagram.
* Blockade problems - will they supply Nicaragua direct or
via a third party.
concerning the following equipment:
1) PAD X3 (Packet Assembler Disassembler)
For connection to RACSAPAC in Costa Rica. We plan to use 4 MODEMs and
use the other ports for system management and connections to
university networks.
X25 port capable of 2400 and 4800 baud, preferably 9600 as well. 8
serial ports RS232 (or 4 extendable to 8) at least 1200 baud,
preferably 2400 as well.
We understand that some PADs are stand alone units and some are plug
in cards for PCs and compatables. We would like information about both
sorts but we are especially interested in the latter because we would
like to be able to run software that would connect the caller either
to RACSAPAC via the PAD or to some other system of our own via a RS232
port, e.g. a local BBS or packet radio gateway.
2) MODEM "A"
Synchronous modem for the X25 link. At least 4800 baud, preferably
9600 too.
3) MODEM "B"
Bell standard modem for the incoming calls. Bell 212A is suitable.
We'd like to know how much extra a MNP (class 5?) facility would be.
4) MODEM "C"
An economical Bell standards, Hayes compatable modem capable of 1200
duplex, for re-sale to our customers.
We will be grateful for anything you can find out or any other advice/
comments.
The best way to send stuff to us varies. Our address is given below
