Internal Modem
The optional built-in modem on the KE200 is a Bell 103J/212A compatible answer modem.
The KE200 supports a 2400 baud internal modem, which is part of the modem kit (P/N
C06319).
The modem is designed for 0-300, 1200, or 2400 baud, full duplex, asynchronous
communication. The modem is mounted inside the KE200 system at the factory. Power for the
modem is supplied by the KE200 system.
The modem is designed to meet or exceed the direct connection registration requirements of
the FCC rules. This means the modem will connect directly with a jack supplied by the phone
company. The customer has to order this jack and have it installed. To order this equipment
from the phone company, specify the following:
• Any one of the following jacks: RJ11C or RJ41S, or RJ45S.
• The registration number of 6BHUSA-24793-DT-E.
• The data transmission rate of 0-300 baud, 1200 baud, or 2400 baud.
• The Bell equivalent of 103J/212A.
