||
| 10 | |||
| 11 | 3 | laforge | As can be seen clearly on the picutre, it uses the [[CologneChip_HFC|CologneChip HFC-8S]] 8-port S/T interface IC. There's a lattice glue logic chip for interfacing with the backplane bus, and the analog frontend + magnetics sections for 8 ports. Four ports have jumper blocks to change the NT/TE cross-over, while the other 4 ports are static. |

| 31 | 2 | laforge | |
| 32 | 4 | laforge | The S2M (PRI) module is centered around an Infineon PEF2256E FALC56 chip. This is one of the most common E1 framers on the market. |
| 33 | |||
| 34 | The glue logic for interfacing with the backplane/bus is implemented in a Xilinx CPLD. |
