Juniper Networks T1600 - Manual (Page 43)

• Unframed in-band loopback at CSU
• Unframed in-band loopback at Smartjack (ANSI)
• You can configure the following framing modes using the CLI:
• T1—SF (D4/superframe), ESF (extended superframe)
• E1—G704, G704–no-crc4, unframed
• Packet buffering, Layer 2 parsing
• Local line, remote line, and remote payload loopback testing; each channel can be looped
individually and independently of other channels (DS1/E1 channels)
• Simple Network Management Protocol (SNMP): T1 MIB (RFC 1406)
• Dynamic, arbitrary channel configuration
• Full bit error rate test (BERT)
• Clocking: internal and loop (clock recovered from network and use for transmit). Internal timing
is the default for channelized T1 ports. The external master clock can be a multiple of 2.048
MHz or 1.544 MHz for E1 or T1 operation.
• Line coding:
• T1—CLI configurable as AMI or B8ZS
