mindspeed technologies ? 1 proprietary and confidential evaluation module - m28500/29503/ 26910 errata product affected: m28500/ 29503/26910 sonet chipset evaluation module the purpose of this document is to describe the following: ? sonet/sdh functionality change requirement changes ds3/e3 framer on board part revision changes sonet/sdh functionality change temporarily, sonet sdh functionality has been removed from the sonet chipset evaluation module. only electrical ds3 and e3 modes are operational (i.e. operating modes 1- 6). the user guide refers to the cx29610 device, which is not supplied wi th the board at this time, and therefore, all sonet/sdh-relate d modes and actions should be avoided. should the user attempt to use a sonet/sdh featur e of the board, the resu lts will be undefined and may hang the system. requirement changes mindspeed technologies no longer supplies an ibm pc compatible motherboard with the sonet evaluation module boar d. the user must supply a pc that meets the following requirements: one empty pci 2.1 1 compliant slot. intel i8255x-based ethernet card plus network cable. one floppy drive. 28500-ERR-001-A may 2003
2 mindspeed technologies ? 28500-ERR-001-A proprietary and confidential evaluation module - m28500/29503/26910 errata ds3/e3 framer on board the evaluation module contains the cx28344 quad ds3/e3 framer, and accompanying liu units. this device is not supported by the evm software, but may be used for direct hdlc over ds3/e3 functionality. the device is accessibl e via the cx28500 ebus using such driver functions as mlcn850xcopyuint32rangearraytoebus(). the ?byteenabled? value 2 used to access the cx28344 is 0xb. part revision changes the evaluation module board contains the following parts: (1) pci 2.1 compliant slots have both 5v and 3. 3v power supplies. the evm must have both. (2) this value is used as chip-select in the evm board. part # - rev quantity description data sheet reference cx28500-12 1 1024-channel hdlc controller 28500-dsh-002-a cx29503-13 1 ds3/e3 broadband acce ss multiplexer 29503-dsh-002-a cx28344-11 1 quad ds3/e3 framer 28348-dsh-001-b cx28333-18 1 triple-port ds3/e3 liu 28333-dsh-003-a cx28332-18 2 dual-port ds3/e3 liu 28333-dsh-003-a
