78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.3 Neighbour networks | |
78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.3.1 Specification context | An E&PoC BSS may need to operate in the presence of neighbour networks of other compatible E&PoC devices. Neighbour Network (NN) is an entirely autonomous association of E&PoC devices, which are operated autonomously. Typically, an E&PoC BSS involving several rSTA belonging to one same device - e.g. multi-chipset switc... |
78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.3.2 Requirements | Table 4: Neighbour networks E&PoC Receiver Device (rDEV) Requirement 5.3.1 Any two receiver stations (rSTAs) belonging to a same receiver device (rDEV) shall never join the same E&PoC BSS. Requirement 5.3.2 Any two receiver stations (rSTAs) belonging to different receiver devices (rDEV) shall never join the same E&PoC ... |
78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.4 Security in E&PoC system | |
78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.4.1 Specification context | A typical E&PoC system may be made of hundreds of camera devices. One should keep in mind that changing the Password/NMK of some of the STAs in the system may significantly increase the overall system maintenance, as the list of the several Password/NMK used in the system should be recorded and maintained. Therefore, a... |
78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.4.2 Requirements | Table 5: Default Password/NMK E&PoC Receiver Station (rSTA) / E&PoC Edge Station (eSTA) Requirement 5.4.1 An E&PoC STA (both rSTA and eSTA) shall implement the default E&PoC Password/NMK value provided in Table 6 or Table 7. Table 6: E&PoC default Password Item Parameter Symbol Value 1 E&PoC Default Password 0 Password... |
78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.5 Receiver Device (rDEV) per-port PoC reset | |
78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.5.1 Specification context | In case an eDEV software is stalled, it may be valuable to perform a hardware reset of this device. Such hardware reset may be performed remotely by performing rDEV port power OFF / power ON. ETSI ETSI TS 105 176-2 V1.1.1 (2019-06) 16 |
78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.5.2 Requirements | Table 8: Receiver Device (rDEV) per-port PoC reset (Conditional) E&PoC Receiver Device (rDEV) Requirement 5.5.1 When the Power over Coax (PoC) supply is turned off for one port of an rSTA connecting one or more eSTAs, in an initial E&PoC BSS, all the other E&PoC STAs (both the rSTA and eSTAs connected on the remaining ... |
78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.6 Support to installation (Optional) | |
78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.6.1 Specification context | Installing one or more E&PoC Terminal eDEVs according to a daisy-chain topology requires for the installer some minimum knowledge on the eDEV's typical and maximum power consumption. |

78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.7.1 Specification context | The data streaming - such as video streaming - sent by the eDEV to the rDEV is considered as a highly critical information. Losing some of this information, even temporarily, would have significant impact on the user experience and is therefore considered as not acceptable. This is why the addition of a new eDEV to any... |
78562718753e0d19d95686376ba8abd8 | 105 176-2 | 5.7.2 Requirements | Table 10: Hot-Plug support E&PoC Edge System (eSYS) Requirement 5.7.1 Adding a new eSYS to an existing E&PoC BSS shall not cause any data communication error to the existing data communication currently operated over this E&PoC BSS.
