Chapter 1 Introducing the ZyXEL Device
• "W" denotes wireless functionality. There is an embedded mini-PCI module for IEEE
802.11g wireless LAN connectivity. All wireless features documented in this user's guide
refer to the "W" models only.
• "L" denotes the PSTN (Public Switched Telephone Network) line feature. The PSTN line
lets you have VoIP phone service and PSTN phone service at the same time. All PSTN
line features documented in this user's guide refer to the "L" models only.
When the ZyXEL Device does not have power, the phone(s) connected to the
PHONE port(s) can still be used for making PSTN calls. Only one phone can
be in use at a time.
• Models ending in "1", for example P-2802HWL-I3, denote a device that works over the
analog telephone system, POTS (Plain Old Telephone Service). Models ending in "3"
denote a device that works over ISDN (Integrated Services Digital Network).
Only use firmware for your ZyXEL Device's specific model. Refer to the label
on the bottom of your ZyXEL Device.
All screens displayed in this user's guide are from the P-2802HWL-I1 model.
See the appendix on Product Specifications for a full list of features.
1.2 Ways to Manage the ZyXEL Device
Use any of the following methods to manage the ZyXEL Device.
• Web Configurator. This is recommended for everyday management of the ZyXEL Device
using a (supported) web browser.
• Command Line Interface. Line commands are mostly used for troubleshooting by service
engineers.
• FTP for firmware upgrades and configuration backup/restore.
• SNMP. The device can be monitored by an SNMP manager. See the SNMP chapter in this
User's Guide.
• SPTGEN. SPTGEN is a text configuration file that allows you to configure the device by
uploading an SPTGEN file. This is especially convenient if you need to configure many
devices of the same type.
• TR-069. This is an auto-configuration server used to remotely configure your device.
