The MD12 receives and transmits 32xE1 signals and works with the
PEG8 to process E1 CES and ATM/IMA services.
Table 1 provides the functions and features of the MD12.
Table 1 Functions and features of the MD12
Function and Feature
MD12
Basic functions
Transmits and receives 32xE1 signals, and works with the PEG8 to
process E1 CES and ATM/IMA services.
Interface types
Supports 120-ohm E1 electrical interface. The electrical interface
uses the DB44 connector.
Interface characteristics
Loopback types of the port
Inloop
Outloop
Non-loopback
Auto disabling of port loopback
Supported
CES
Number of CES services
32
Emulation mode
CESoPSN, SAToP
Jitter compensation buffering time
The jitter compensation buffering time of CES services can be set
to a value in the range of 0.375 ms to 16 ms with a step of 0.125
ms.
Packet loading time
The packet loading time of CES services can be set to a value in
the range of 0.125 ms to 5 ms with a step of 0.125 ms.
NOTE:
The packet loading time needs to be set to the same value for the
NEs at both ends.
The jitter compensation buffering time needs to be more than at
least two times of the packet loading time.

Supported
Clock function
Restores four CES adaptive clock recover (ACR) clocks.
Clocks that are recovered from services over ports 1 and 9 can be
added to the clock priority list.
NOTE:
Clock recovery over ports 1 to 16 is independent of clock recovery
over ports 17 to 32. That is, clocks that are recovered from
services over ports 1 to 16 can be transmitted out of ports 1 to 16
and clocks that are recovered from services over ports 17 to 32 can
be transmitted out of ports 17 to 32.
Clock mode
Line Clock Mode and Null.
Line code of E1 link
HDB3 code
Frame format of E1 link
Unframed format, double-framed format, or E1 CRC-4 multiframe
format (default value)
Maintenance features
Supports the query of the board manufacturer information.
Supports the in-service loading of the FPGA.
Supports the upgrade of the board software without affecting
services.
Supports the PRBS function. For details, see Availability.
