1-Port T1/E1 Mini-PIM for SRX

The 1-Port T1/E1 Mini-Physical Interface Module (Mini-PIM) provides the physical connection to T1 or E1 network media types and also performs T1 or E1 framing and line-speed signaling.
The 1-Port T1/E1 Mini-Physical Interface Module (Mini-PIM) provides the following key features:

• Channel service unit/data service unit (CSU/DSU) to eliminate the need for a separate external device
• 56-Kbps and 64-Kbps operating modes
• Independent internal and external clocking option
• Alarm reporting with a 24-hour history maintained
• Loopback, BERT, FDL (T1 only), and Long Buildout (T1 only) diagnostics
• Multilink Frame Relay and Multilink PPP support

The 1-Port T1/E1 Mini-Physical Interface Module (Mini-PIM) has the following loopback diagnostics:

• Local, remote, payload
• Test patterns (BERT)
• All ones
• All zeros
• Alternating ones and zeros (AA/55)
• 1:3 or 1-in-4 pattern
• 1:7 or 1-in-8 pattern
• 3:24 - 3 bits set in every 24 bits
• QRSS20 (Modified PRBS 2^20-1, with 14 zero suppression)
• PRBS 2^7-1 - PRBS 2^9-1 (as specified in ITU-T O.153)
• PRBS 2^11-1 (as specified in ITU-T O.153)/2047 pattern
• PRBS 2^15-1 (as specified in ITU-T O.151/O.153)
• PRBS 2^20-1 (as specified in ITU-T O.153)
• Programmable word or 32-bit programmable pattern
• Network (T1) alarm
• LOS, LOF, AIS, YLW
