EMISSION REQUIREMENTS
FCC CLASS A
Warning: Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of FCC rules. These limits are designed
to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at
his own expence.
CANADIAN EMISSIONS
This digital apparatus does not exceed the Class A limits for noise emmissions from
a digital apparatus set out in the Radio Interference Regulations of the Canadian
Department of Communications.
Le present appareil numerique n’emet pas de bruits redioelectriques depassant les
limites applicables aux appareils numeriques de la Class A prescites dans le
Reglement sur le brouillage redioelectrique edicte par le ministere des
Communications du Canada.

1-1 OPERATION
CHAPTER 1 - OPERATION
The 1206P (CTS ME-X.21) is a cost effective solution for interconnection of X.21
terminal devices located in proximity of each other. The use of two modems is
eliminated with a resulting cost savings to the user. The 1206P (CTS ME-X.21)
complies with the CCITT V.11 balanced interface specification. Two 15 pin DB-15
connectors are provided to interface to the X.21 terminals.
Clocking
Clockingatratesupto768Kbpswiththelowspeedversionandupto2.048MbpswithHigh
