Client Cannot Reach Router

Table5-7, IPC-to-Router Segment, examines the IPC-to-R outer segment of the

network on the IPC end of the segment.

Table 5-7. IPC-to-Router Segment

Layer Solution

Layer 1 –

Physical 1. On the IPC, make sure the cables are firmly attached to the WAN

interface.

2. If no CSU/DSUs are being used, either the router or the IPC must provide

network clocking. Network clocking is usually provided by the device

connected to the DCE cables.

3. If no CDU/DSUs exist between IPC and Router, make sure transmission

lines are active by looking for appropriate LEDs.

4. If there is no connection between the router and IPC, invert the clocking

on one or both DSU/CSUs.

Layer 2 –

Network On the IPC:

1. Set payload scramble to false. To turn PLScramble on or off on the IPC,

type map slot/port (where slot/port is that of the ATM card) and set 10=1

to false.

2. If using SONET, make sure that the line characteristics are correct. Type

map slot/port and select the Phy Media option.

3. Enter vas to make sure a service is configured.

4. Make sure encapsulation is the same as on the router (RFC1483).

5. Enter vvc to make sure vpi and v ci are configured correctly.

6. Enter vcs to view ATM connection statistics.

7. Enter vcrs and vcts to view transmitted and received cells.
