NOTICE: For information on pinout assignments for this connector, refer to
Supervisory Port Pin Assignments on page A-9. See Ordering
Information on page A-5 for information on cables for this connector.
10/100 Ethernet
The FrameStart FSM provides one 10/100 ETHERNET interface. This interface
is an eight-pin modular jack that complies with standard twisted-pair,
10/100Base-T requirements. The 10/100Base-T cable is supplied by the end
user. Refer to Ethernet Connection Pin Assignments on page A-8 for pin
assignments and cable descriptions.
Ethernet LED Indicators
There are two unlabeled indicator LEDs on either side of the
10/100 ETHERNET jack. The LED on the left side of the jack pulses amber to
indicate data activity (either transmit or receive). The LED on the right side of
the jack lights green to indicate that the link layer is operational.
Serial Interface
The SERIAL INTERFACE located on the rear of the unit is a multi-protocol
interface presented physically as a DB-25 connection. The protocols supported
by this interface are RS-232, EIA-530, and V.35. Cables that adapt the DB-25
interface to the 34-pin V.35 interface are available. These cables are optional
equipment and their part numbers are listed in Optional Equipment on
page A-5. There are also DB-25 to DB-25 cables available if your installation
needs require them. See Ordering Information on page A-5 for details. Pin
assignments for the Serial interface are listed in Serial Port Interface Pin
Assignments on page A-8.
CAUTION: FCC rules require that interconnecting cables carrying high-speed
data be shielded appropriately to minimize radio frequency
interference.
Network Interface
Labeled on the rear panel of the FrameStart FSM as NET , this interface
connection is a standard RJ-48C, 8 -pin modular jack that contains an
automatic line build out (ALBO) allowing the unit to be located a substantial
distance away from the telco network interface with a receive signal level to
−
27 dB. To view the pinout assignments for this connection, refer to Network
Interface Pin Assignments on page A-8.
The Network interface transmit LBO level should be set as instructed under
Line Build-Out (Long Haul) on page 3-5. Maximum suggested cable lengths
for the connection from the unit to the network are listed in the table below.
