Section 1, Introduction MX2800 STS-1 User Manual
Telnet
4. TELNET
Telnet provides a password-protected, remote login facility to the MX2800 STS-1 that allows a remote
user to control the MX2800 STS-1 through the terminal menus. Only one Telnet menu session may be
active at a time.
5. TL1
Transaction Language 1 (TL1) is an ASCII based language that supports both command-response and
autonomous (NE) message generation. Commonly, TL1 is used over a X.25 packet network but is
completely independent of any physical layer protocols. For the MX2800 STS-1, TL1 is implemented as a
Telnet session running over either Ethernet or PPP. Up to eight TL1 Telnet connections may be active at a
time.
6. AVAILABLE OPTIONS
The following optional equipment is available for use with the MX2800 STS-1. Contact a local distributor
or the ADTRAN sales department for more information.
Breakout Panel (P/N 1200291L1)
The optional breakout panel connects to the MX2800 STS-1 and provides 28 RJ connectors for the individ-
ual T1s/E1s. Shipment includes two six-foot, 64-pin to 64-pin amphenol cables which allow direct cabling
to the MX2800 STS-1 (refer to Connecting the Breakout Panel on page 2-5 for more information).
BNC Patch Panel (P/N 1200291L5)
The optional BNC Patch Panel connects to an MX2800 Chassis or equivalent and is mountable to a
19-inch rack. The panel converts the T1/E1 transmit-and-receive signal interfaces from 120-ohm amphe-
nol interfaces to 75-ohm coaxial (BNC). This allows easy 75-ohm impedance-matched access to both the
transmit and receive lines of each T1/E1 channel. Each of the twenty eight BNC interfaces is configurable
as either balanced or unbalanced. The frame ground of the patch panel is connected to a ground lug acces-
sible on the rear of the patch panel. See Figure 1-2.
