E1 Interfaces Feature Guide for Routing Devices configuration into the current candidate configuration. The example does not become active until you commit the candidate configuration. If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example is a full example. In this case, use the load merge command. If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In this case, use the load merge relative command.
About the Documentation commit { file ex-script-snippet.xsl; } 2. Move to the hierarchy level that is relevant for this snippet by issuing the following configuration mode command: [edit] user@host# edit system scripts [edit system scripts] 3. Merge the contents of the file into your routing platform configuration by issuing the load merge relative configuration mode command: [edit system scripts] user@host# load merge relative /var/tmp/ex-script-snippet.

E1 Interfaces Feature Guide for Routing Devices You can configure an E1 interface or a CE1 or E1 partition on a channelized PIC to execute a bit error rate test (BERT) when the interface receives a request to run this test.

Possible completions: pseudo-2e11-o152 Pattern is 2^11 -1 (per O.152 standard) pseudo-2e15-o151 Pattern is 2^15 - 1 (per O.151 standard) pseudo-2e20-o151 Pattern is 2^20 - 1 (per O.151 standard) pseudo-2e20-o153 Pattern is 2^20 - 1 (per O.
E1 Interfaces Feature Guide for Routing Devices To explicitly configure G704 framing, include the framing statement at the [edit interfaces interface-name e1-options] hierarchy level, specifying the g704 option: [edit interfaces interface-name e1-options] framing g704; By default, G704 framing uses CRC4.
Chapter 2: E1 Interfaces loopback to be local or remote. With local loopback, the E1 interface can transmit packets to the CSU, but receives its own transmission back again and ignores data from the CSU. With remote loopback, packets sent from the CSU are received by the E1 interface, forwarded if there is a valid route, and immediately retransmitted to the CSU.

Chapter 2: E1 Interfaces There are 32 time slots on an E1 interface. Time slot 0 is always reserved for framing and cannot be used to configure a fractional E1 interface. Time slot numbering constraints vary for different E1 PICs, as follows: • For 4-port E1 PICs, the configurable time slot range is 1 through 31 (time slot 0 is reserved for framing).

CHAPTER 6 Interface Diagnostics • Interface Diagnostics on page 85 • Interface Diagnostics Operational Mode Commands on page 92 Interface Diagnostics You can use two diagnostic tools to test the physical layer connections of interfaces: loopback testing and bit error rate test (BERT) testing. Loopback testing enables you to verify the connectivity of a circuit. BERT testing enables you to identify poor signal quality on a circuit.
E1 Interfaces Feature Guide for Routing Devices There are several types of loopback testing supported by the Junos OS, as follows: • DCE local—Loops packets back on the local DCE. • DCE remote—Loops packets back on the remote DCE. • Local—Useful for troubleshooting physical PIC errors. Configuring local loopback on an interface allows transmission of packets to the channel service unit (CSU) and then to the circuit toward the far-end device.

E1 Interfaces Feature Guide for Routing Devices To configure BERT, you must configure the duration of the test, the bit pattern to send on the transmit path, and the error rate to monitor when the inbound pattern is received.
Chapter 6: Interface Diagnostics NOTE: The 12-port T1/E1 Circuit Emulation (CE) PIC supports only the following algorithms: all-ones-repeating Repeating one bits all-zeros-repeating Repeating zero bits alternating-double-ones-zeros Alternating pairs of ones and zeros alternating-ones-zeros Alternating ones and zeros pseudo-2e11-o152 Pattern is 2^11 -1 (per O.152 standard) pseudo-2e15-o151 Pattern is 2^15 - 1 (per O.151 standard) pseudo-2e20-o151 Pattern is 2^20 - 1 (per O.
E1 Interfaces Feature Guide for Routing Devices NOTE: BERT is supported on the PDH interfaces of the Channelized SONET/SDH OC3/STM1 (Multi-Rate) MIC with SFP and the DS3/E3 MIC.
Chapter 6: Interface Diagnostics These limitations do not apply to channelized IQ interfaces. For information about BERT capabilities on channelized IQ interfaces, see Channelized IQ and IQE Interfaces Properties. Starting and Stopping a BERT Test Before you can start the BERT test, you must disable the interface.
E1 Interfaces Feature Guide for Routing Devices } } Interface Diagnostics Operational Mode Commands Table 6 on page 92 summarizes the command-line interface (CLI) commands you can use to run diagnostics on router interfaces. Commands are listed in alphabetical order. Table 6: Interface Diagnostics Operational Mode Commands 92 Task Command Start a bit error rate test (BERT) on a DS0 interface. test interface ds0-bert-start Stop a BERT on a DS0 interface.
