MSC8102 Packet Telephony Farm Card (MSC8102PFC)
The MSC8102 packet telephony farm card (MSC8102PFC) is a PCI telephony mezzanine card (PTMC) for evaluating media gateway products.
This card is designed around the StarCore™ MSC8102 16-bit fixed-point DSP device.
On the MSC8102PFC is a DSP farm consisting of five MSC8102 devices and one MSC8101 device to aggregate the data to/from the DSP farm.
Each MSC8102 device has an associated 4M × 32 (16 MB) SDRAM.
The MSC8101 aggregator has a separate 2 M × 32 (8 MB) SDRAM.
The MSC8102PFC interfaces with a baseboard platform via its PTMC site (see Figure 1).
The PTMC is a PCI Mezzanine Card (PMC) module that conforms to the PMC standard for Jn1 and Jn2 but uses Jn3 and Jn4 to support a variety of telecommunications interfaces.
The PTMC site on the media gateway is configured similar to a PT3MC, a subset of the PTMC specification that supports UTOPIA, Ethernet Reduced Media-Independent Interface (RMII), and computer telephony bus interfaces on Jn3/4.
An optional fifth connector (Jn5) is added to support the two MII interfaces supported by the MSC8101 device.
Jn5 is a proprietary connector, effectively supporting an enhanced PTMC that is backward-compatible with existing PTMCs.
