PoE Function
eSpace 6805 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 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 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 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 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 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 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 Servers (ACS). It includes both a safe auto
configuration and the control of other CPE management functions within an integrated
framework.
