Configuring The Ds3 Uni Module - 3Com 3C63100-AC-C - PathBuilder S600 Bridge/router Reference Manual

Configuring the DS3
UNI Module
Number of VPI for VCC—The number of distinct VPIs that can be used for
VCCs on this card: 1..256. The remaining VPIs are available for VPCs.
Xmt Ckt ID—The transmit path trace identifier. This is a user-entered identifier
for the transmit circuit of up to either 16 characters (if Sonet Interface Mode is
set to STM-1) or 64 characters (if Sonet Interface Mode is set to OC3). The path
trace is a byte used to repetitively transmit a 64-byte fixed length string so that
a receiving terminal in a path can verify its continued connection to the
intended transmitter.
c Select [8] Previous Menu to return to the OC3/STM-1 Configuration menu.
3 Configure virtual interfaces for the OC3/STM-1 UNI card.
a Select [2] Virtual Interfaces to open the OC3/STM-1 Virtual Interfaces
Configuration menu. This menu is the same as the MCPU Virtual Interfaces
menu, shown earlier in Figure 83.
b Configure virtual interfaces as described under "Configuring Virtual Interfaces"
earlier in this chapter. You configure virtual interfaces for the OC3/STM-1 UNI
card in the same way that you configure virtual interfaces for the MCPU card,
except that you can configure 24 VIs total for the OC3/STM-1 UNI card, as
opposed to 2 for the MCPU card.
Configuring the DS3 UNI module involves the following tasks:

To configure the DS3 UNI module, follow these steps:
1 From the List Card menu, select the slot number corresponding to the DS3 UNI
module to display the DS3 UNI Configuration menu.
The DS3 UNI Configuration menu is the same as the OC3/STM-1 UNI
Configuration menu shown earlier in Figure 88. The options on this menu allow
you to access other menus from which you can configure either card configuration
information or virtual interfaces.
2 Configure the DS3 card.
a Select [1] Card Information to display the DS3 UNI Card Configuration menu.
The DS3 Card Configuration menu is similar to the OC3/STM-1 UNI Card
Configuration menu shown earlier in Figure 89. It displays the current
configuration for the DS3 module and provides options for changing certain
parameters.
b Set the following parameters as desired:
Admin Status—Administrative Status: In Service or Out of Service.
LBO Length—Line Build Out length. The signal generation/regeneration of the
distance between the PathBuilder S600 and the next crossconnect or FOTs
(Fiber Optic Terminal system), in feet: 0-225 or 225-450.
DS3 Framing Mode—The type of frame organization configured for the
specified port interface: Cbit or M23. Set this parameter to match the framing
type offered by your service provider. Cbit is the most common setting, as its
use of overhead bits for administration and maintenance allows the service
provider more visibility in isolating any issues with the physical line connections
through the WAN. You must match this setting at the two ends of the DS3
trunk.
