Q. What is the purpose of the Reset button?
A. The Reset button is used to restore the router to the default factory settings if pressed within 5 seconds of router power up. Here is how it works:
• The router will not react to the Reset button if it is pressed 5 seconds or more after power up.
• When the Reset button is pressed within 5 seconds of bootup and there is no valid xxx.cfg file in the flash memory, the router boots up with the factory defaults stored in nonvolatile RAM (NVRAM).
• When the Reset button is pressed within 5 seconds of boot up and there is a valid xxx.cfg file in the flash memory, the router boots up with the xxx.cfg file and avoids the startup-config file in NVRAM. The xxx.cfg default configuration file in flash memory also replaces the startup-config file in NVRAM.
Q. What is the function of the virtual auxiliary port?
A. On the Cisco 860 and 880 Series, the console port supports modem control signals. When an external modem is connected to this port, you can use this interface for out-of-band remote management of the router or as a backup WAN interface. An optional RJ-45 to DB-25 male straight-through cable is available to connect modems to this port. A limited set of modems and terminal adapters has been tested, but you can use any Hayes-compatible modem or terminal adapter to connect to this port. The console port behaves like a standard Cisco auxiliary (AUX) port if configured as such and can provide bit rates up to 115.2 kbps.
Q. What locking cables do you recommend for use with the security cable lock?

Q. Will the Cisco 860 and 880 Series DSL models work with any DSLAM?
A. Refer to the DSLAM interoperability document for a list of supported DSLAMs.
Q. What is Annex M?
A. Annex M is an enhancement of the G.992.3 standard that doubles the upstream bandwidth by "borrowing" 32 additional tones from the downstream frequency range. This feature enables service providers to provision symmetric data rates for ADSL2 and ADSL2+ services with data rates up to 2 Mbps. The achievable upstream rates are a function of loop length and specific DSLAM Annex M implementation.
Q. What does the term "mask" imply in Annex M?
A. The mask refers to the submode power-spectral-density (PSD) mask applicable for Annex M. Service providers use the mask to minimize the cross-talk between adjacent pairs to an acceptable level. G.992.3 specifies the masks, as shown in Table 3.
Table 5. Annex M Masks
Q. What mask does Cisco 887M support?
A. Cisco 887M is optimized for Mask M 9. It can operate in other masks, but the performance may be lower than that of a CPE that is optimized for that mask.
