5.0 CONFIGURATION
All configuration is done through software
The LAN port also requires no configuration to connect to a 10BaseT Ethernet.
Note: The V.35 Interface is configured as a DTE. The 2135 will transmit and receive data to and from the DCE, based on the speed of the clocks received from the DCE.
On the LAN side interface, data is sent and received in burst mode at 10Mbps.
5.1 LED STATUS MONITORS
The 2135 uses two LEDs on the Ethernet connection side. A green LED indicates that link connection to the network is established. The yellow LED displays status codes (See section 5.1.2 for status code information).
Seven, low power, LEDs located on the top of the 2135 case indi- cate POWER and V.35 signal activity.
5.1.1 LAN side LEDs
The Model 2135 features two LAN LEDs that monitor general operation status and the 10BaseT twisted pair link integrity. Figure 4 shows the LEDs located at the rear of the Model 2135. Following Figure 4 is a description of each LED function. Figure 5 shows the LEDs located on the top of the Model 2135.

5.1.2 LED Descriptions
The status LED blinks yellow from one to eleven times to indicate system status. Each pulse pattern is separated by a 2 second "off " peri- od. Greater pulse patterns have higher priority (buffer saturation has greater priority than an empty MAC table).
Valid system statuses are:
1 pulse | = | system status ok | |
2 pulses | = | No MAC entries in the MAC address table | |
3 pulses | = | Clear to send (CTS) or Carrier Detect (DCD) from | |
base unit are not asserted | |||
4 | pulses | = | IMRC2/IA buffer is saturated |
5 | pulses | = | WAN receive frame(s) too large |
6 | pulses | = | WAN receive frame(s) not Octet aligned |
7 | pulses | = | WAN receive frame(s) aborted |
8 | pulses | = | Detected WAN receive frame(s) with bad CRC |
9 | pulses | = | Detected LAN receive frame(s) too large |
10 pulses | = | Detected LAN receive frame(s) not Octet aligned | |
11 pulses | = | Detected LAN receive frame(s) with bad CRC |
After a status code is displayed eight times and the associated con- dition is removed, the status code will no longer appear.
The link LED glows green to indicate link integrity on the 10BaseT twisted pair line.
5.1.3 Power and DCE/DTE Interface LEDs
Seven LEDs indicate POWER and DTE/DCE activity on the front of the 2135.
