• Transmitting 1-point contact signal through NTT
(Nippon Telephone & Telegraph) personal telecom-
munication line of 50 b/s • Approved of Technical
Requirements Compliance Approval by Japan Ap-
proval Institute for Telecommunications Equipment
• Approval No. M90-N227-0 • Applicable to vari-
ous cables types • No interference by induction noise
• Lightning protection applicable • No field adjust-
ment required • Compact plug-in construction easy
to install and maintain
*24V DC (Code R) and 12V DC (Code S) are not ap-
proved by Japan Approvals Institute for Telecommu-
nications Equipment.
Therefore an individual application will be necessary
for using the TMA on NTT telecom. line.
