Viewing Channelization Properties
MToP encapsulates TDM streams for delivery over packet-switching networks (PSNs) using the
following methods:
• SAToP—A method for encapsulating TDM bit-streams (T1, E1, T3, or E3) as pseudowires over
PSNs.
• CESoPSN—A method for encapsulating structured (NxDS0) TDM signals as pseudowires over
PSNs.
For T1 or E1 entries, the TDM properties presented in Table 20-9 are displayed in physical inventory in
addition to the existing T1 or E1 properties.
Viewing Channelization Properties
Prime Network Vision supports the channelization of SONET/SDH and T3 lines. When a line is
channelized, it is logically divided into smaller bandwidth channels called paths. These paths (referred
to as high order paths or HOPs) can, in turn, contain low order paths, or LOPs. The sum of the bandwidth
on all paths cannot exceed the line bandwidth.
For SONET show and configuration commands, see Configuring SONET, page 20-53.
The following topics describe how to view channelization properties for SONET/SDH and T3 lines:
• Viewing SONET/SDH Channelization Properties, page 20-18
• Viewing T3 DS1 and DS3 Channelization Properties, page 20-21
Table 20-9 TDM-Specific Properties for DS1 (T1 or E1) in Physical Interfaces
Field Description
International Bit Whether or not the international bit is used by the controller:
• 0—The international bit is not used.
• 1—The international bit is used.
This property applies only to E1.
National Bits Whether or not the national reserve bits (sa4, sa5, sa6, sa7, and sa8) are used
by the controller:
• 0—The national reserve bits are not used.
• 1—The national reserve bits are used.
This property applies only to E1.
Line Code Line encoding method for the DS1 link:
• For E1, the options are Alternate Mark Inversion (AMI) and
high-density bipolar of order 3 (HDB3).
• For T1, the options are AMI and bipolar with 8 zero substitution (B8ZS).
Cable Length For T1 ports in short-haul mode, the length of the cable in feet.
