ds3
Syntax [no] ds3 [sonet-sdh-index]
Context config>port>tdm
Description This command enables the context to configure DS3 parameters on a 2-port OC3/STM1
Channelized Adapter card or a 4-port DS3/E3 Adapter card.
DS3 lines carry 28 DS1 signals and a 44.736 Mb/s data rate.
If DS3 links are provisioned on a channelized SONET/SDH Adapter card, you must provision
the parent STS-1 SONET/STM0 SDH path first (this requirement does not apply to the 4-port
DS3/E3 Adapter card).
The no form of this command disables DS3 capabilities on the specified SONET/SDH path
or DS3 port. The DS3 parameters must be disabled if a clear channel is enabled by default.
A clear channel uses out-of-band signaling, not in-band signaling; therefore, the entire bit rate
of the channel is available.
Default n/a
Parameters sonet-sdh-index — specifies the components making up the specified SONET/SDH path
on the 2-port OC3/STM1 Channelized Adapter card
e1
Syntax [no] e1 e1-id
Context config>port>tdm
Description This command enables the context to configure E1 parameters on a channelized 16-port
T1/E1 ASAP Adapter card, 32-port T1/E1 ASAP Adapter card, 2-port OC3/STM1
Channelized Adapter card, 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card, or 4-port
DS3/E3 Adapter card (DS3 ports only). E1 is a standard WAN digital communication format
designed to operate over copper facilities at a rate of 2.048 Mb/s.
Once a channel has been configured for E1, all ports on the card can only be configured for
E1. There cannot be a mix of DS1 and E1 channels on the same card.
The no form of this command deletes the specified E1 channel.
Default n/a
Parameters e1-id — the identifier of the E1 channel
Values E1 number (1 to 21) | e1-sonet-sdh-index
