Remote-Installation Design
The ZyXEL IES-1248-51V can operate in the environment with temperature from
-40°C to 65°C, which meets various Fiber-to-the-Node and Fiber-to-the-Curb
environment conditions worldwide. A side-slip plug-in and pull-out mesh filter,
which is cleanable and reusable, is equipped to make it dust-proof and suitable
for open-air installations.
Moreover, the rotational speed of the fan module is automatically adjusted
according to the system temperature. The feature not only extends the lifespan
of the module, but also has lower audible noise, which is important if
IES-1248-51V is installed in a residential neighborhood. The fan module is
swappable in order to reduce the maintenance cost in the field.
Complete ADSL2+ Services
The IES-1248-51V provides state-of-the-art ADSL2+ connectivity to subscribers.
The latest technologies like various line coding, power spectral mask fitting,
dual latency path selection, loop diagnostic and power management capabilities,
Seamless Rate Adaptation (SRA) and Impulse Noise Protection (INP) are all
supported. Up to 24Mbps (downstream) and 2.3Mbps (upstream) per port facilitates
high-bandwidth services such as streaming video, online gaming and IP TV. ADSL2+
port bonding is also provided for subscribers who need even more bandwidth or
located with loop length longer than 5000 ft.
VoIP Media Gateway Embedded
The IES-1248-51V has a built-in POTS splitter and can act as the media gateway
of a packet voice network. Through the communication with the softswitch or
media gateway controller, IES-1248-51V digitalizes and encapsulates the POTS
voice into VoIP packets and delivers them to the IP network with higher priority
in SIP or H.248 signal protocols. Telco operators can provide voice over
broadband (VoBB) service without changing existing customer premises network and
keep the OAM&P as usual.
Sophisticated Features for Triple-Play Services
The IES-1248-51V comes with complete ATM and Ethernet QoS, as well as various IP
QoS features (Packet classification/Rate Limitation/Queue Scheduling). The
seamless QoS-mapping not only allows consistent and appropriate traffic
treatment of packets, but also enables fulfillment of triple-play services.
The number of the supported multicast groups is 512, while each group can have
50 members. At least 30 multicast IGMP join/leave requests can be processed in
one second and the maximum channel processing time is less than 250 ms. For
security, anti MAC address spoofing, broadcast storm prevention, MAC count
limiting and packet filtering features are provided. With these features
provided, Telco operators can easily offer Triple-play services like high-speed
Internet access, VoIP, Near VOD, Broadcast TV and TV on Demand.
