For bulk data transfers, I'm not aware of anyplace in the world where X.25
public packet services are competitive with high-speed dialup modems over
long distance dialup. X.25 is quite expensive for bulk data, since in most
countries you more than offset the low connect time charges with high traffic
(packet or segment) charges.

In Canada, you can call Faspac (416)/232-6781 or Datapac (613) 781-0978 and
ask them. I believe SprintNet and Accunet now have operations in Canada as
well. I've found Datapac, SprintNet, and Accunet all excruciatingly difficult
to work with -- you can never get ahold of the right person (Datapac), or the
people don't have a clue as to what they're doing (SprintNet), or they just
got re-org'd (again) and haven't figured out who they are working for or what
their job is yet (Accunet). I haven't tried talking to Faspac.

Here is a rough guideline as to what you would pay:

Assuming you are using Datapac 3000 service (Telecom Canada's 
do-it-yourself PADing service) with a 2400 baud connection you 
can figure on paying 
(per Month):

	Packet Charges:			$306.00/mo
	Basic Access Charge:		$440.00/mo (2 nodes @ $220.00 ea)
					----------
					$746.00/mo

In addition, you will have to pay some $500.00 in initial service 
charges, plus you will have to buy two PADs (several thousand dollars 
each?) or lease them. If you lease them from the phone company, you 
are using Datapac 3101 and you can depend on a higher monthly bill 
(too grumesome for me to figure out exactly). GST, PST and other taxes 
extra.

Also note that if you do not fill your packets (256 bytes each), your 
packet charges will increase porportionally.

Call your local phone company to get the Datapac connect information.

COMPUTATION OF RATES (from 'Datapac Rates' #132 07/89):
[ 1 Packet = 256 Bytes, 1 Kp = 1000 Packets = 256 000 Bytes ]

Rate Between Vancover and Toronto:	$1.70/kilopacket
Data Transfered:
	1 - 2 Mb/day 	= 1.5 * 30
			= 45/Mb month	
			~=		180 Kp/mo
					(assuming optimal transmission,
					no overheads)

Packet Costs/Month:
	180 Kp * $1.70/Kp = 		**** $306.00/mo ****

Datapac 3000 Service Charges:
	2400 bps			**** $220.00/mo ****
	4800 bps			$325.00/mo
	9600 bps			$465.00/mo
