firmware versions from flash volume, the 833IS will then still run in factory mode
upon bootup.
Instead of initial configuration being performed over a direct serial connection, the
833IS configures IP parameters through the front panel of the unit. The 833IS is able
to configure the IP Address, gateway, subnet mask and LAN speed from the front
panel enabling connections to be established across the LAN (Ethernet or Token
Ring). The 833IS can then be accessed by a console through a Telnet session.
Although Cisco products allow access to internal resources such as queues and
buffer sizes, Perle has protected these internal resources and restricts users from
modifying them to maintain the integrity and quality of the product.
The interface mapping on the 833IS differs from that on the Cisco router. The card’s
BRI interfaces are 0 based from 0 to 7 (e.g. the first 4 BRI interfaces are located on
card 1 mapped 0-3, the second 4 BRI interfaces are on card 2 mapped 4-7). On the
833IS, commands that are applied to a specific interface will be applied all interfaces
that reside on the card. When interactively executing commands to a specific
interface, notification messages are displayed indicating which interfaces have been
modified. For example, the following command at the global configuration level
will set all interfaces in the router to Northern Telecom DMS-100 switch type:
isdn switch type basic-dms100
The following commands will set the BRI interfaces 4-7 to DMS-100 and sets
interfaces 0-3 to 5ESS since the
interface bri 0
command applies to all
interfaces residing on the same card.
isdn switch type basic-dms100
interface bri 0
isdn switch type basic-5ess
A notification message will be displayed indicating what interfaces have been
modified:
“Parameter change applies to all interfaces numbered from 0-3.”
The 833IS handles WAN interfaces differently than Cisco products. Cisco
configures IP parameters for each individual WAN interface on the unit. Each WAN
interfaces on a Cisco product is considered an individual entity connected to a router
which then routes to a device on a LAN.
