Come on and DSLAM!

Two Siemens Surpass DSLAMs, one ADSL one VDSL.

mciancia, implr and q3k are looking at this.

Access

Lab ADSL DSLAM (HiX 5620 A50) can be reached by telnet 185.236.240.67 2137 from boston-packets or the space LAN.

FXS

We have a companion FXS rack device, Audio Codes MP-124D/FXS/AC. It's currently at q3k's place.

Components

  • Main MCU: PowerQUICC MPC860PZQ80D4
  • Line interface: 12x PEB3264 and PEB4266
  • Custom ASICs (codecs?): 6x AC482-C (three more footprints unpopulated)

PSU Recap

The caps on the PSU (APSI-605AC Rev.C) are bad. Here's the values jotted down so that q3k can order some new ones:

Refdes Capacitance Voltage Diameter Height Lead spacing Replacement
C9, C10, C14 470uF 63V 16mm 20mm 7.5mm EEU-FS1K471S
C15, C17, 220uF 100V 16mm 25mm 7.5mm UHE2A221MHD6TN
C19, C20, C22 1200uF 10V 10mm 20mm 5mm EEU-FS1E122B

C19 is bulged. C10 is burst. The rest look fine (after desoldering, no, the bottom plugs are also slightly pushed out on some of the others - good call to replace them regardless), but should be replaced regardless.

There's also a primary side 100uF/400V cap (C13) that has been measured to be ~97uF, which is good enough so is left alone for now.
