| 3 | 15 | laforge | @laforge bought three Livingston Portmaster 3 PM3A-1E, which are RAS (Remote Access Server) that |
| 4 | 2 | laforge | * terminates one 1E line (30 B-channels) |
| 5 | * provides ISDN dial-up on those channels |
||
| 6 | * provides DSP based modems in case analog modem calls should be handled. |
||
| 7 | |||
| 8 | 15 | laforge | One unit (rbbs-pm3) is part of the [[retro-bbs:Dialup_Network_In_A_Box]], another unit (pm3-2) is part of the [[octoi:Colocated_Hub]], the third one is at @laforge's basement. |

| 31 | h3. DSP / Modem Board |
||
| 32 | |||
| 33 | There are 6 slots for modem boards, each board typically has 10 soft-modems, resulting in a total capacity of maximum 60 modems (equalling the number of B-channels in 2 E1 PRI links) |

| 39 | |||
| 40 | There is a set of expansion headers on the mainboard which, according to the hardware installation guide, can accommodate a "compression or accelerator card". The compression card is model PM3-CMP and allows Stac compression to run on up to 60 channels. |

||
| 48 | |||
| 49 | 7 | laforge | The original fan is a Fonsan DFB0812M (DC 12V 0.1A) fan by DELTA ELECTRONICS INC. The specs seem to state 2600 RPM / 24.8 dB(A) / 29 cfm. |
| 50 | 6 | laforge | |
| 51 | I found it too noisy and replaced it with a Noctua NF-A8 FLX with L.N.A (reduced to 1650 rpm / 12.9 dB(A) / 24 cfm) |
||
| 52 | |||
| 53 | 1 | laforge | Fun fact: The PM3 actually seems to have a 5V -> 12V DC/DC upconverter just for the fan - instead of simply using a 5V fan... |

| 55 | h3. Power Supply |
||
| 56 | |||
| 57 | 16 | laforge | One of the PM3A-E1 at @laforge had a broken power supply. The oroginal PSU is an ASTEC LPS1112 rated for 5V/22A output (80W convection cooled, 1120W with 30cfm forced air). |
| 58 | 7 | laforge | |
| 59 | 17 | laforge | It was replaced with a Mean Well LRS-150F-5. Mechanical assembly via a custom adapter plate that was fabricated easily from a small piece of aluminium sheet metal (175 x 102 mm) with a few drill holes. |

| 81 | |||
| 82 | h3. route to different telpnet hosts based on called party number |
||
| 83 | |||
| 84 | Assuming one wants to use a PM3 to act as modem bamk for accessing differnt [virtualized] BBSs over telnet, the problem is how to route the inbound call to a specific telnet IP address. The non-radius stand-alone configuration of the PM3 only permits either: |
||
| 85 | * automatic forwarding of all calls to one global telnet/rlogin host |
||
| 86 | * allowing the users to enter the hostname for telnet themselves |
||
| 87 | 11 | laforge | * providing a list of pre-configured telnet desinations to all users (this was used at the 36C3 retronetowrking installation, see [[retro-bbs:36C3]]) |
| 88 | 1 | laforge | |
| 89 | 11 | laforge | |
| 90 | 10 | laforge | However, with the _Call-Check_ radius feature, it should be possibl to receive the called + calling identity before the call is even accepted, and the nin return provide the telnet IP/port to which the call shall be routed. |
