Configuring the 1-Port Channelized OC-3/STM-1 SPA and 1-Port Channelized OC-12/STM-4 SPA
Purpose
Creates a logical channel group on an E1 line, where:
• e1#—A number in the range of 1 to 3.
• channel-group—Defines a logical channel group to be a channelized
E1 line.
• channel-group#—Specifies the channel group number.
• list-of-timeslots—Specifies the number of timeslots that make up the
E1 line.
• speed [56 | 64]—Specifies the line speed in kilobits per second. Valid
values are 56 and 64
Creates an E1 unframed (clear channel) logical channel group on an E1
line, where:
• e1#—A number in the range of 1 to 3.
Sets the type of framing (including unframed) used by an E1 line, where:
• e1#—A number in the range of 1 to 3.
• crc4—Specifies 4-bit cyclic redundancy check (CRC) framing.
• no-crc4—Specifies basic framing.
Sets the clock source on an E1 line, where:
• internal—Specifies that the internal clock source is used.
• line—Specifies the E1 line as the clock source.
Sets the national reserved bits on an E1 line, where:
• e1#—A number in the range of 1 to 3.
• pattern—A hexadecimal value in the range 0x0 to 0x1F (hexadecimal)
or 0 to 31 (decimal).
Specifies a loopback on an E1 line, where:
• e1#—A number in the range of 1 to 3.
• local loopback—(Optional) Loops data from the transmit path to the
receive path.
• network loopback—(Optional) Loops data received on the external
port to the transmit path and back out the external port.
