T3/E3 ATM Mezzanine Card (PMC)
Description To support T3/E3 ATM functions, a T3/E3 ATM PCI Mezzanine card (PMC) must
be installed in slot 1 on the Carrier Expansion Card. The T3/E3 ATM PMC is a
customized card designed to be mounted only on the Vanguard 7300 Carrier
Expansion Card. This PMC cannot be installed anywhere else. Figure2-19 on
page 2-29 shows the PMC mounted on the Carrier Expansion Card.
Note
The T3 ATM PMC Card is only supported in slot 1 of the Carrier Expansion
Card. Due to the design of the T3 ATM Rear Transition Module, only the top slot
of the Carrier Expansion Card supports the T3 ATM PMC.
Functions The T3/E3 ATM PMC converts data to and from ATM cells and transfers the cells to
and from host memory over the PCI bus. The T3/E3 ATM PMC provides these
functions:
• ATM over T3/E3 with a PCI host interface
• User Network Interface (UNI) to T3/E3
• Support for RFC2496 T3/E3 MIB
ATM Compression Support
Introduction Release 6.3 and greater supports the use of compression on a Vanguard 7300 Series.
Prior to release 6.3 ATM was not designed to support compression over an AAM
station (connecting via PVC to LCON stations).
