79 | ** 1x E1 to icE1usb/clock-source |
||
80 | 20 | laforge | ** 2x E1 used with loop-back cable to provide proper timing from master card to slave card (timing cable has residual clock drift) |

82 | |||
83 | 4 | laforge | h3. icE1usb / E1 clock source (1U / 31cm) |
84 | 1 | laforge | |
85 | 4 | laforge | This is a 1U rack mount system containing: |
86 | * a PC-Engines APU3 embedded x86_64 |
||
87 | * an [[e1-t1-adapter:ICE40_E1_USB_interface|icE1usb]] with a custom RS422 interface board |
||
88 | * a custom rs422 over voltage protection + 12V injection board |
||
89 | 1 | laforge | |
90 | 4 | laforge | This icE1usb acts as a GPS-disciplined clock master. However, as no acutal RF GPS signal is available in the data centre, we are using an Ericsson [[ericsson-rbs-6xxx:GPS_02]] attached via ~100m of RS-422. |

127 | h2. Roof installation |
||
128 | |||
129 | |||
130 | On the roof of the data centre, the CAT5 cable with RS422 for the GPS03 arrives. |
||
131 | |||
132 | It will be passed through several DIN rail mounted OVP (Over Voltage Protection) circuits before connecting to the actual DIN-rail mounted Ericsson GPS03 |
||
133 | |||
134 | The Ericsson GPS03 has a SMA connector, to which a SMA-male to N-Male coaxial cable is attached. |
||
135 | |||
136 | A Times Microwave LP-GTR-NFF lightning protector (N-female to N-femaile) is used to pass the coaxial cable through the enclosure |
||
137 | |||
138 | An external GPS antenna with N connector is plugged into the LP-GTR-NFF |

173 | |||
174 | 3 | laforge | * Like in the current hub at @laforge's basement, we should run the entire yate / osmo-e1d / dahdi-trunkdev inside a KVM with SRV-IO mapping the PCI devices |

189 | h2. Misc / TODO |
||
190 | |||
191 | h3. local verification with modem/ISDN-TA |
||
192 | |||
193 | It would be great if we could somehow verify local calls via the yate / hub excluding the complexity of the TDMoIP to compare calls without TDMoIP to calls with TDMoIP. |
||
194 | |||
195 | Unfortuantely I'm not aware of any really small PBX that would terminate the E1/S2M and offer S0/POTS ports. Adding antoher 3U for a PBX seems excessive. |
||
196 | |||
197 | 1 | laforge | Doing calls between PM3 and ASR5400 is of course an option, but ideally we'd have a real physical modem attached via a serial port, and a real HFC-S-USB for test purpose. |
198 | 11 | laforge | |
199 | h2. High-level parameters for data centre |
||
200 | |||
201 | * 7U rackspace |
||
202 | * 7x AC power outlet |
||
203 | 13 | laforge | * 7x Ethernet switch port (one of which supports 10 MBps!) |
204 | 11 | laforge | ** some ports in a new VLAN |
205 | ** some ports in an existing VLAN of my other servers in Rack 1120 |
||
206 | * 1x CAT5 between rack and roof |
||
207 | * about 10cm of space on DIN-rail on roof enclosure (to mount OVP + GPS03) |
||
208 | |||
209 | h2. Questions |
||
210 | 1 | laforge | |
211 | 12 | laforge | * Required antenna cable length between rooftop enclosure and antenna |
212 | * Mechanical antenna mounting details |
||
213 | 11 | laforge | * detailed switch port / VLAN config |
