FLEXIBILITY
An enterprise’s need for applications and speed dictate flexible and scalable solutions. The PA-MC-STM-1 enables customers to scale services
by upgrading bandwidth from DS0 to E1 connections—all without changing the port adapter in their Cisco 7000 series routers. The additional
ability to support “convenience” DS0 connections is an important factor for some end users who are planning to increase capacity in the future,
but require continued support for today’s existing connections.
KEY FEATURES
• One channelized STM-1 port
• Channelized E1, fractional E1, and full-rate E1 supported
– Up to 256 usable channels can be allocated among the 63 E1 ports
– Internal or network clocking selectable on each E1
– 64 kbps DS0 time slots
• Line and payload loopback capabilities—local and network at the E1 and STM-1 level
• Full bit-error-rate testing capabilities on any E1
– Programmable pseudo-random pattern up to 32 bits in length including 2 11-1; 2 15-1; and 2 20-1, 0153, and QRSS
– 32-bit error count and bit-count registers
– Detect test patterns conform to ITU-T 0.151 and 0.152 standards
• Alarm detection—Full SDH alarms and MIBs and E1 alarms and MIBs (AIS, Remote Alarm, FEBE, OOF, and so on)
• Online insertion and removal (OIR) of the VIP
• Supports CEF/distributed CEF switching
• Supports MLPPP and Distributed MLPPP
• Support for the following serial encapsulation protocols:
– Frame Relay

• Support for the following networking protocols:
– IP
– IPX
• 16-bit or 32-bit CRC4 supported
• Support for 1+1 SDH Multiplex Section Protection (MSP) as per G.783 Annex A
E1 SPECIFIC FEATURES
• Alarm detection—CRC errors, UAS, OOF, LOF, AIS, error seconds, and so on
• Alarm reporting—24-hour history maintained, 15-minute intervals on all errors
• Internal and loop (recovered from network) clocking
