Is USB ADSL suitable for BCD?
No.

Are ISDN and dial up Internet service suitable for
BCD?
You may use ISDN or dial up Internet for BCD with an appropriate IP
router (e.g. Planet IRT-101 IP router for ISDN). However, the voice
quality will be affected due to the instability to data in traditional
telephone network. Moreover, you are advised to keep your Internet line
active for 24 hours for incoming call reception. Sometimes it will be
high in service charge if you are keeping an ISDN Internet line active
for 24 hours.

Is dynamic IP Internet service good for BCD?
Yes. If the customer is using a dynamic IP Broadband Internet service at
one side (e. g. China) and a fixed IP service at another side (e.g.
Manila), he can use the internal roaming service in the BCDs to link the
2 sides. If both sides are using dynamic IP services, he needs to
subscribe to a roaming service. The roaming service is a charged
service.

Can the user talk via the BCD while other users
are using Internet?
Yes. An IP sharing router should be used (e.g. Planet XRT-101 IP
Router).

How much bandwidth is used by the BCD?
The BCD will consume bandwidth only when it is in conversation mode. The
bandwidth for voice data is 5.33 K bps. The actual bandwidth consumption
per voice channel is voice data + IP overhead = 12 - 13 K bps

How many BCDs can a customer install?
For normal Broadband Internet service, one BCD per IP. If the ADSL
service used by the customer provides one IP only, the customer can only
install one BCD. For IPLC or VPN network, there is no limitation on the
number of BCD installed. It is because we can use private IPs within the
IPLC network and install as many BCD as we want.

When does the customer need roaming?
A roaming service is provided to BCD customers when all the sites are
using dynamic IP Broadband services. There is a minimal service charge
per year per BCD. Customer is required to pay for the first year.
However, if the customer has 8 sites (or less) and one out of them is
using fixed IP Broadband service, roaming is not required. The customer
can use the built-in roaming feature in the BCD. No service charge is
incurred.

When is the IP router required?
The IP router allows the customer to use the BCD (voice) and the other
PCs (data) at the same time. It uses only one IP for more than one
applications. It is required for single IP Internet line (e.g. Cable,
ADSL). For IPLC and VPN network, multiple IPs are provided in normal
cases, the IP router thus is not required.

Can the BCD work behind a Firewall?
No. If a Firewall is installed in the network, you should open a two-way
channel (hole) without any security blockage in the Firewall for the
BCD's IP. You may simply put the BCD before the Firewall while the other
PCs are behind the Firewall.

Can the customer install multiple BCDs if a
multiple IP Broadband line is used?
Yes. Each BCD consumes one IP address. If the customer can provide
several IPs (public), he can install several BCDs.

How many speed dialing keys are provided by the
BCD?
Eight. To activate a speed dialing key, the caller can press [##1] to
[##8].
Back to top
Will a BCD be started automatically after a power
failure?
Yes. All settings in the BCD are stored in non-volatile flash memory.
When the power is restored after a power failure, the BCD will resume
normal operation automatically without any loss in system data. However,
the BCD needs to re-login the data network (e.g. Internet or LAN) after
a power failure. Therefore, the data network should also be ready after
a power failure.
