In the Cisco 7000 series or Cisco 7500 series routers, the PA-MC-E3 requires the following VIP models:
![]() |
Caution The VIP requires that the host Cisco 7000 series router has the RSP7000 and RSP7000CI installed. The VIP will not operate properly with the Route Processor (RP), Switch Processor (SP), or Silicon Switch Processor (SSP) installed in the host Cisco 7000 series router. |
In the Catalyst 5000 family switches, the PA-MC-E3 requires the following Catalyst RSM/VIP2 module:
![]() |
Note While the VIP2 and Catalyst RSM/VIP2 support online insertion and removal, individual port adapters installed on a VIP2 or Catalyst RSM/VIP2 do not. To replace port adapters you must first remove the VIP2 or Catalyst RSM/VIP2 from the chassis, then replace port adapters as required. Port adapters have a handle attached, but this handle is occasionally not shown in this publication to allow a full view of detail on the port adapter faceplate. The Cisco 7200 series routers support online instertion and removal of the PA-MC-E3. |
In the Cisco 7200 routers or Cisco uBR7200 series routers, the PA-MC-E3 port adapter does not support the NPE-100.
For port adapter hardware and memory configuration guidelines for Cisco 7200 series routers, refer to the document Cisco 7200 Series Port Adapter Hardware Configuration Guidelines.
This condition only effects the initially released version of the PA-MC-E3 (Hardware Version 3.1.0) and will be fixed with the release of Hardware Version 3.1.1. To determine the hardware revision of your installed PA-MC-E3, issue the show controllers e3 command and observe the following line:
CE3 H/W Version : 3.1.0
The symptom of this condition is the reception by an E1 line of a persistent receive alarm indication (RAI) signal from the far end that cannot be attributed to any other failure in the external network between the PA-MC-E3 and the far end. To recover from this condition, you must manually shut down the affected E1 line, and then immediately bring it back up. Do this by executing the following commands (in succession), which are available in the E3 controller configuration mode:
e1 e1-line-number shutdown no e1 e1-line-number shutdown
Following is an example of this shutdown/no-shutdown operation for E1 line 5 of an PA-MC-E3 on a VIP2 in interface processor slot 2:
Router# config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller e3 2/0/0
Router(config-controller)# e1 5 ?
bert Start BERT test
channel-group Specify the timeslots to channel-group mapping for an E1
interface
clock Specify the clock source for an E1
framing Specify the type of Framing on an E1 line
loopback Put an E1 line into loopback
national Specify the National Reserved bits for an E1
pri-group Configure the specified timeslots for PRI
shutdown Shut down an E1 interface
unframed Unframed E1
Router(config-controller)# e1 5 shut
Router(config-controller)# no e1 5 shut
If the preceding operation does not resolve the problem, you might need to repeat the operation a second time to recover from this loss-of-frame (LOF) state.
![]() |
Note The E1 line shutdown command will not be accepted while running BERT or loopbacks; these functions must be stopped first. In addition, a BERT or loopback cannot be started while an E1 line is shut down. |
Following are safety guidelines that you should follow when working with any equipment that connects to electrical power or telephone wiring.

Follow these basic guidelines when working with any electrical equipment:
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.
Following are guidelines for preventing ESD damage:
![]() |
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm). |
The MC-E3 port adapter is designed to conform to the regulatory approvals listed in Table 2-2 and the standards approvals listed in Table 2-3.
| Regulatory Approval | Requirement |
|---|---|
Network homologation | Pulse mask and jitter requirements with respect to E3 per ITU-T G.703 and G.823, ETSI TBR24, and BAPT 221 ZV MU 11. |
Safety | EN 60950, EN 41003 |
Emissions (Radiated) | Per EMC Directive, the appropriate IEC/ETSI, CISPR 22 requirements |

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

Note The PA-MC-E3 port adapter has been designed to meet these requirements. Modifications to this product that are not authorized by Cisco Systems, Inc., could void the various approvals and negate your authority to operate the product. |
The BABT607116 marking on the PA-MC-E3 signifies that it meets United Kingdom directive 607116 and has been designed to BABT standards. The BABT label is located on the top of the PA-MC-E3; Figure 2-1 shows the BABT label for the PA-MC-E3.

ITI-T recommendation G.823 specifies that it is important to restrict jitter gain. Figure 4 of G.823 shows a typical jitter transfer characteristic. (Note that small jitter gain is allowed.) British Standard 328: Section 8.1 1990 gives the allowable gain as 0.5 dB.
The PA-MC-E3 line mode clocking complies with these sections.
When the PA-MC-E3 is in line clocking mode, jitter is not attenuated, and any jitter received is transferred to the line. If input jitter exceeds the limits of TBR24, then output jitter will not meet TBR24 transfer specifications. Line clocking mode is intended for use only where the connection involves a single hop, and where clock timing will not be transferred to other network equipment.
When not in line clocking mode, the PA-MC-E3 complies with TBR24 standards.
