MSC711x Packet Telephony Farm

Card (SPT711xPFCE)

The MSC711x packet telephony farm card (SPT711xPFCE)

accelerates time to market of MSC711x DSP voice over

internet protocol (VoIP) designs. This card contains a farm of

four StarCore?-based MSC711x DSP devices aggregated

through a ten-port Ethernet switch and interfacing with a

computer telephony (CT) bus carrying up to four TDM

streams. The board meets the common mezzanine card

(CMC) specification for a single-width form factor. Two

separate CMC connector sites, one on each side, provide the

pin connections for two different development platforms.

The board is designed to connect to the Freescale Packet

Telephony Development Kit (PDK) and the Freescale

Modular Development System (MDS). Both development

platforms are designed with Freescale PowerQUICC?

processors. One side has three CMC connectors placed as

described in the CMC specification, plus a fourth

non-standard CMC connector for additional signalling. The

other side has all four standard CMC connectors. All

power/ground and most signal connections match the PCI

telecom mezzanine card (PTMC) specification (type 3).

The devices can boot standalone through an on-board I 2 C

EEPROM or under external host control through the host

processor bus interface. Typical data flow converts VoIP

traffic from the Ethernet switch to the TDM bus and

generates VoIP traffic using data from the TDM bus.
