PoE Function
eSpace 6805, eSpace 6810,eSpace 6830, eSpace 6850, and eSpace 6870 support the PoE
function. When not being connected to a power adapter, a client can obtain power from a PSE
device (a PoE switch such as the Quidway S3900 Series) to work normally. eSpace 6805,
eSpace 6810, eSpace 6830, eSpace 6850, and eSpace 6870 support the mode of free-line
power supply and mode of signal-line power supply. When the PoE function is used, the
reliable power supply distance is up to 100 meters.
Bridging Function
eSpace 6805, eSpace 6810,eSpace 6830, eSpace 6850, and eSpace 6870 support the bridging
function. The device connected to the PC interface of an IP phone can access the network
connected to the LAN interface of the IP phone and can communicate with other devices in
the network. In this case, the IP phone acts as a switch with two interfaces but the working
mode is different from the working mode of a normal switch. Special configurations are
performed at the lower layers of an IP phone to separate the broadcast packets between the
two interfaces. Therefore, the IP phone is not affected by a large number of broadcast packets.
DSP Functions
The DSP chip of eSpace 6805, eSpace 6810,eSpace 6830, eSpace 6850, or eSpace 6870
supports comfort noise generation (CNG) and voice activity detection (VAD). These functions
are controlled by the DSP automatically, which can be set on Web pages. You can enable this
function by selecting Yes in Silence Suppression on the ACCOUNT page of the Web
configuration interface.
VLAN Functions
eSpace 6805, eSpace 6810,eSpace 6830, eSpace 6850, and eSpace 6870 support the VLAN
function. The packets sent by an IP phone are labeled with tags. In this case, the packets can
be transmitted through a separate voice VLAN so that the stability of VOIP packets is
ensured.
QoS Functions
The eSpace-series IP phones support the Layer 2 QoS technology based on 802.1q and 802.1p
and the Layer 3 QoS technology based on ToS. The deployment of QoS on the VoIP bearer
network ensures the voice quality during the transmission.
PPPoE Function
eSpace 6805, eSpace 6810,eSpace 6830, eSpace 6850, and eSpace 6870 support the PPPoE
dialing function. By using the PPPoE user name and password that are preset on an IP phone,
the IP phone can initiate the PPPoE dialing and set up a connection with the softswitch
through ADSL. In this way, the VoIP conversation is set up successfully.
TR-069 Function
eSpace 6805, eSpace 6810,eSpace 6830, eSpace 6850, and eSpace 6870 support Technical
Report 069 (TR-069). TR-069 is a DSL Forum technical specification entitled CPE WAN
Management Protocol (CWMP). It defines an application layer protocol for remote
management of end-user devices. As a bidirectional SOAP/HTTP-based protocol, it provides
the communication between customer-premises equipment (CPE) and Auto Configuration
